It's time to write our first program.
0:02
We've written some Python code
0:04
and we play around with it in the REPL
0:05
but that doesn't really count.
0:07
What we want is something that we can save
0:09
and run again on command
0:11
and it just does whatever our program does.
0:13
We're going to do this using PyCharm Community Edition.
0:17
So I'm going to go and launch that here.
0:18
And PyCharm Community, is 100% free
0:21
and it's available on macOS, Windows and Linux.
0:23
So you should be able to use this, no problem.
0:26
There's also a paid version but we don't need it
0:28
for this course.
0:29
We want to going to go create a new project
0:31
and then we're going to create our M&M game.
0:34
So we'll say, M&M.
0:36
Now it's suggesting that we create a new virtual environment.
0:38
And lets just let it go ahead and do that here.
0:41
This is all fine. This is a way to create isolated environments.
0:44
So if we install other libraries
0:45
they don't interact or conflict with other programs
0:49
we might be working on.
0:50
Technically it's not needed but it's the default.
0:52
So I'm just going to go with it.
0:53
Later, we might use that.
0:55
We'll talk more about it near the end of the course
0:57
but right now we're not going to use other libraries
0:59
so it doesn't matter.
1:00
Right now, here we are
1:01
and we don't have any way in seeing
1:03
You see over here this is grayed out.
1:04
We don't have any way to run our program.
1:07
So lets go over here and create our first Python file.
1:10
So go over here and say, Right click, save new
1:13
add on file. And we can call it anything we want.
1:15
Lets just call it something like guessinggame, like this.
1:20
So over here we have our little game.
1:21
And lets just make sure everything's working.
1:23
Lets just do our little hello world trick.
1:25
Like this, we'll just print, Hello world.
1:27
And notice there's a little squiggly here.
1:29
PyCharm verifies that our code
1:31
is meeting the Python standards.
1:33
There's certain rules about how we should write our code
1:36
how we should name our variables and so on.
1:38
One of the rules is it should end in a new line, blank line.
1:42
If you hover over it, it says
1:43
No new line, the end of file.
1:45
Then we'll just hit enter and that will go away.
1:46
So there's nothing wrong with the program.
1:48
It just happens to be PyCharm saying
1:50
this is technically probably going to work
1:52
but it doesn't quite follow the standards.
1:54
Now in order to run this and use this little button
1:57
that looks like it should run something
1:58
you have to right click on the file and say
2:00
Run guessinggame or whatever you called it.
2:03
And then it runs down here at the bottom.
2:05
You can see, Hello world and any input
2:07
or other stuff that's going to happen
2:09
is always going to happen in PyCharm down here.
2:12
If you'd like to, you could always just copy this command here
2:15
and run it in the terminal, if you like.
2:17
But for the most part
2:19
just seeing the output happen down at the bottom
2:21
is what we're going to need. Alright.
2:23
Well, this is creating our project.
2:25
And yeah, it's not yet the M&M guessinggame
2:27
but we're going to get there.
2:28
But this is the first step.
2:29
Make sure that we can use our editor and save this stuff.
2:32
This way we can make changes through our existing code
2:35
and re-run it and see the changes here.
2:37
We don't have to like keeping typing it back into the REPL.
2:40
Woo, that's a good thing.
