what’s going on everybody and welcome to a go programming tutorial series this
a go programming tutorial series this
a go programming tutorial series this tutorial series is going to be practical
tutorial series is going to be practical
tutorial series is going to be practical and applied but also over the basics of
and applied but also over the basics of
and applied but also over the basics of go the reason why I want to do it that
go the reason why I want to do it that
go the reason why I want to do it that way is because the go programming
way is because the go programming
way is because the go programming language I mean all programming
language I mean all programming
language I mean all programming languages are like this but the go
languages are like this but the go
languages are like this but the go programming language because it’s kind
programming language because it’s kind
programming language because it’s kind of a low-level programming language it’s
of a low-level programming language it’s
of a low-level programming language it’s kind of the case that you could go
kind of the case that you could go
kind of the case that you could go through a basics tutorial for something
through a basics tutorial for something
through a basics tutorial for something like go and feel like you kind of
like go and feel like you kind of
like go and feel like you kind of understood what was going on and then
understood what was going on and then
understood what was going on and then you actually go to try to apply it to a
you actually go to try to apply it to a
you actually go to try to apply it to a project or something and you’re like I
project or something and you’re like I
project or something and you’re like I have no idea how to do this right so so
have no idea how to do this right so so
have no idea how to do this right so so my hope is that each time we learn
my hope is that each time we learn
my hope is that each time we learn something we’re going to apply it to an
something we’re going to apply it to an
something we’re going to apply it to an overarching objective and project and my
overarching objective and project and my
overarching objective and project and my hope is that that’ll that’ll make
hope is that that’ll that’ll make
hope is that that’ll that’ll make learning go much much simpler but still
learning go much much simpler but still
learning go much much simpler but still even at the end of that the best way to
even at the end of that the best way to
even at the end of that the best way to learn something is to keep trying to use
learn something is to keep trying to use
learn something is to keep trying to use it to solve various types of tasks so
it to solve various types of tasks so
it to solve various types of tasks so some of that’s actually still going to
some of that’s actually still going to
some of that’s actually still going to be on you but hopefully I can make some
be on you but hopefully I can make some
be on you but hopefully I can make some of that initial process easier so first
of that initial process easier so first
of that initial process easier so first of all why go why would someone like me
of all why go why would someone like me
of all why go why would someone like me be interested and go why might you be
be interested and go why might you be
be interested and go why might you be interested and go basically go is built
interested and go basically go is built
interested and go basically go is built from the ground up it was built by
from the ground up it was built by
from the ground up it was built by Google it was built to solve Google
Google it was built to solve Google
Google it was built to solve Google types of problems right so basically go
types of problems right so basically go
types of problems right so basically go is for scale this would be like a
is for scale this would be like a
is for scale this would be like a systems language web development
systems language web development
systems language web development language anything you want to scale
language anything you want to scale
language anything you want to scale anything you want to be super efficient
anything you want to be super efficient
anything you want to be super efficient but you might not want to write in C++
but you might not want to write in C++
but you might not want to write in C++ so for example the reason I’m interested
so for example the reason I’m interested
so for example the reason I’m interested in go is mainly for web development so a
in go is mainly for web development so a
in go is mainly for web development so a website like Python programming net for
website like Python programming net for
website like Python programming net for example it’s built in Python using flask
example it’s built in Python using flask
example it’s built in Python using flask and it’s not the slowest website in the
and it’s not the slowest website in the
and it’s not the slowest website in the world but it’s also not the fastest
world but it’s also not the fastest
world but it’s also not the fastest website in the world it could we could
website in the world it could we could
website in the world it could we could make some serious speed gains there and
make some serious speed gains there and
make some serious speed gains there and in web development the difference of 100
in web development the difference of 100
in web development the difference of 100 mil or 100 milliseconds is a major
mil or 100 milliseconds is a major
mil or 100 milliseconds is a major difference especially when you scale
difference especially when you scale
difference especially when you scale that out to millions of users so it you
that out to millions of users so it you
that out to millions of users so it you know the speed doesn’t just affect user
know the speed doesn’t just affect user
know the speed doesn’t just affect user the user experience but it also affects
the user experience but it also affects
the user experience but it also affects your bottom line how much are you paying
your bottom line how much are you paying
your bottom line how much are you paying for processing cost basically right in
for processing cost basically right in
for processing cost basically right in hosting time and all of that so anywhere
hosting time and all of that so anywhere
hosting time and all of that so anywhere you can make gains in web development
you can make gains in web development
you can make gains in web development it’s usually a very good thing and then
it’s usually a very good thing and then
it’s usually a very good thing and then the bigger the scale the better those
the bigger the scale the better those
the bigger the scale the better those are for you also in terms of just
are for you also in terms of just
are for you also in terms of just anything where you need it to be super
anything where you need it to be super
anything where you need it to be super fast or super efficient go is pretty
fast or super efficient go is pretty
fast or super efficient go is pretty much C++ speeds so anywhere well that’s
much C++ speeds so anywhere well that’s
much C++ speeds so anywhere well that’s a good thing to you maybe you’re in
a good thing to you maybe you’re in
a good thing to you maybe you’re in high-frequency trading or something like
high-frequency trading or something like
high-frequency trading or something like that where you you really want to be as
that where you you really want to be as
that where you you really want to be as quick as possible but maybe you don’t
quick as possible but maybe you don’t
quick as possible but maybe you don’t want to write something as tedious as C
want to write something as tedious as C
want to write something as tedious as C so go is gonna be static typed like C++
so go is gonna be static typed like C++
so go is gonna be static typed like C++ unlike Python so every time like in
unlike Python so every time like in
unlike Python so every time like in Python every time the interpreter hits a
Python every time the interpreter hits a
Python every time the interpreter hits a variable has to kind of figure out what
variable has to kind of figure out what
variable has to kind of figure out what is that variable and that variable could
is that variable and that variable could
is that variable and that variable could change types and stuff like that and by
change types and stuff like that and by
change types and stuff like that and by that I mean like int sand floats and
that I mean like int sand floats and
that I mean like int sand floats and strings stuff like that
strings stuff like that
strings stuff like that whereas in go that’s not the case so it
whereas in go that’s not the case so it
whereas in go that’s not the case so it doesn’t need to know all there it
doesn’t need to know all there it
doesn’t need to know all there it doesn’t it basically doesn’t need to
doesn’t it basically doesn’t need to
doesn’t it basically doesn’t need to figure those things out for you
figure those things out for you
figure those things out for you basically you are gonna tell it what
basically you are gonna tell it what
basically you are gonna tell it what type is what type is certain variables
type is what type is certain variables
type is what type is certain variables and all that kind of stuff so that’s
and all that kind of stuff so that’s
and all that kind of stuff so that’s going to give you some speed also it was
going to give you some speed also it was
going to give you some speed also it was just built from the ground up for
just built from the ground up for
just built from the ground up for concurrency whereas Python was kind of
concurrency whereas Python was kind of
concurrency whereas Python was kind of Python was built from the ground up to
Python was built from the ground up to
Python was built from the ground up to be a teaching language right and it just
be a teaching language right and it just
be a teaching language right and it just so happens that it’s so fun and so easy
so happens that it’s so fun and so easy
so happens that it’s so fun and so easy to program with that it got really
to program with that it got really
to program with that it got really really popular but that’s what Python
really popular but that’s what Python
really popular but that’s what Python was made for so pythons got the global
was made for so pythons got the global
was made for so pythons got the global interpreter lock kind of restricting it
interpreter lock kind of restricting it
interpreter lock kind of restricting it to one thread yes there are ways around
to one thread yes there are ways around
to one thread yes there are ways around that but that’s like band-aids over a
that but that’s like band-aids over a
that but that’s like band-aids over a bigger issue whereas go is just
bigger issue whereas go is just
bigger issue whereas go is just concurrent right out of the box so stuff
concurrent right out of the box so stuff
concurrent right out of the box so stuff like that is what’s gonna make go faster
like that is what’s gonna make go faster
like that is what’s gonna make go faster but go is much more pleasant to write
but go is much more pleasant to write
but go is much more pleasant to write then something like C++ anyways with
then something like C++ anyways with
then something like C++ anyways with that let’s go ahead and get into it I
that let’s go ahead and get into it I
that let’s go ahead and get into it I think you’ll learn a lot more about
think you’ll learn a lot more about
think you’ll learn a lot more about whether or not you like go by actually
whether or not you like go by actually
whether or not you like go by actually using go and seeing what you think from
using go and seeing what you think from
using go and seeing what you think from there so to get go it’s just go to
there so to get go it’s just go to
there so to get go it’s just go to golang.org head to the downloads and

other than that you’re gonna need some
other than that you’re gonna need some sort of editor I’m gonna be using
sort of editor I’m gonna be using
sort of editor I’m gonna be using sublime text people like to make big
sublime text people like to make big
sublime text people like to make big deals about editors you can use whatever
deals about editors you can use whatever
deals about editors you can use whatever you want you can use notepad for that
you want you can use notepad for that
you want you can use notepad for that matter it doesn’t really matter sublime
matter it doesn’t really matter sublime
matter it doesn’t really matter sublime text is a great editor though so you can
text is a great editor though so you can
text is a great editor though so you can use that if you want that’s what I’m
use that if you want that’s what I’m
use that if you want that’s what I’m gonna be using and let’s go ahead and
gonna be using and let’s go ahead and
gonna be using and let’s go ahead and write our very first go program so I’m
write our very first go program so I’m
write our very first go program so I’m gonna go ahead and move this out of the
gonna go ahead and move this out of the
gonna go ahead and move this out of the way and I’ve just got a simple directory
way and I’ve just got a simple directory
way and I’ve just got a simple directory called go tux so I’m going to go ahead
called go tux so I’m going to go ahead
called go tux so I’m going to go ahead and just make a new file and I’m just
and just make a new file and I’m just
and just make a new file and I’m just gonna call it go to go yes we’re gonna
gonna call it go to go yes we’re gonna
gonna call it go to go yes we’re gonna open that up and we’re gonna get ready
open that up and we’re gonna get ready
open that up and we’re gonna get ready so the first thing in every go program
so the first thing in every go program
so the first thing in every go program it’s gonna be a part of a package and
it’s gonna be a part of a package and
it’s gonna be a part of a package and for the most part you’re gonna find
for the most part you’re gonna find
for the most part you’re gonna find yourself pretty much writing package
yourself pretty much writing package
yourself pretty much writing package mean every time until you start writing
mean every time until you start writing
mean every time until you start writing bigger things
bigger things
bigger things so package main and then you’re gonna
so package main and then you’re gonna
so package main and then you’re gonna have your imports for now we’re just
have your imports for now we’re just
have your imports for now we’re just going to import fmt and all your imports
going to import fmt and all your imports
going to import fmt and all your imports go in double quotes and something to get
go in double quotes and something to get
go in double quotes and something to get used to especially if you’re coming from
used to especially if you’re coming from
used to especially if you’re coming from Python which I assume many people
Python which I assume many people
Python which I assume many people viewing this or from my channel mainly
viewing this or from my channel mainly
viewing this or from my channel mainly watch Python you have to use double
watch Python you have to use double
watch Python you have to use double quotes also you’re putting quotes around
quotes also you’re putting quotes around
quotes also you’re putting quotes around your imports but get rid of single
your imports but get rid of single
your imports but get rid of single quotes you’re gonna be done using them
quotes you’re gonna be done using them
quotes you’re gonna be done using them with with go also if I if I slip up and
with with go also if I if I slip up and
with with go also if I if I slip up and call go python and all that kind of
call go python and all that kind of
call go python and all that kind of stuff I’m sorry it’s gonna happen I’m
stuff I’m sorry it’s gonna happen I’m
stuff I’m sorry it’s gonna happen I’m also probably gonna type like print a
also probably gonna type like print a
also probably gonna type like print a few times I’m also gonna make quite a
few times I’m also gonna make quite a
few times I’m also gonna make quite a few pun puns about go so get used to it
few pun puns about go so get used to it
few pun puns about go so get used to it so once you’ve done your imports we’re
so once you’ve done your imports we’re
so once you’ve done your imports we’re just gonna import fmt which is like
just gonna import fmt which is like
just gonna import fmt which is like format basically it’s gonna be how we
format basically it’s gonna be how we
format basically it’s gonna be how we can print something out basically we’re
can print something out basically we’re
can print something out basically we’re ready to build out our functions so to
ready to build out our functions so to
ready to build out our functions so to actually write a function you’re gonna
actually write a function you’re gonna
actually write a function you’re gonna say func that just start your function
say func that just start your function
say func that just start your function you’ve got your function name
you’ve got your function name
you’ve got your function name you’ve got parameters and then the
you’ve got parameters and then the
you’ve got parameters and then the function comes after that
function comes after that
function comes after that again it’s not Python unfortunately
again it’s not Python unfortunately
again it’s not Python unfortunately we’ve got braces so like many other
we’ve got braces so like many other
we’ve got braces so like many other languages so and then in here you write
languages so and then in here you write
languages so and then in here you write your code we’re just gonna have some
your code we’re just gonna have some
your code we’re just gonna have some simple code it’s just going to be FM T
simple code it’s just going to be FM T
simple code it’s just going to be FM T capital P print line and then we’re just
capital P print line and then we’re just
capital P print line and then we’re just going to say again in double quotes
going to say again in double quotes
going to say again in double quotes don’t use single quotes anymore welcome
don’t use single quotes anymore welcome
don’t use single quotes anymore welcome to go awesome so we can go ahead and
to go awesome so we can go ahead and
to go awesome so we can go ahead and save that and let’s run this program
save that and let’s run this program
save that and let’s run this program real quick so we’re going to come
real quick so we’re going to come
real quick so we’re going to come here I’m gonna open up the command line
here I’m gonna open up the command line
here I’m gonna open up the command line and to run it you just do go run and
and to run it you just do go run and
and to run it you just do go run and then whatever the file name is so for me
then whatever the file name is so for me
then whatever the file name is so for me it’s go touch go go hey dinner and but
it’s go touch go go hey dinner and but
it’s go touch go go hey dinner and but welcome to go so that’s going to go
welcome to go so that’s going to go
welcome to go so that’s going to go ahead and compile and run it for you at
ahead and compile and run it for you at
ahead and compile and run it for you at the same time so so that’s that not too
the same time so so that’s that not too
the same time so so that’s that not too much I really want to cover here until
much I really want to cover here until
much I really want to cover here until we get to the next tutorial like I said
we get to the next tutorial like I said
we get to the next tutorial like I said there’s just like a little things that
there’s just like a little things that
there’s just like a little things that you’ll have to get used to also you
you’ll have to get used to also you
you’ll have to get used to also you might be wondering why did the main
might be wondering why did the main
might be wondering why did the main function even run like we didn’t ask it
function even run like we didn’t ask it
function even run like we didn’t ask it to run great question so we’ll be
to run great question so we’ll be
to run great question so we’ll be talking about stuff like that in the
talking about stuff like that in the
talking about stuff like that in the next tutorial also be explaining a lot
next tutorial also be explaining a lot
next tutorial also be explaining a lot of little smaller things here that you
of little smaller things here that you
of little smaller things here that you might not have noticed if you have
