Mastering PyCharm Transcripts
Chapter: PyCharm Projects
Lecture: Creating projects
0:01 Let's start by creating a new project.
0:04 Now, I would normally just open a PyCharm and create the project
0:08 but I want to make sure that you have everything that we're doing in this course
0:12 so remember, our github repository over here,
0:15 I'm going to clone this really quick just to take you through the whole life cycle
0:20 so we'll come over here, we'll go to our desktop
0:23 and we're going to clone this using the git command.
0:26 We could do this with PyCharm
0:28 but you'll see there's one piece that maybe gets missed
0:31 that I really like to do when we're getting started,
0:33 but I'll show you where you could clone this from PyCharm directly.
0:38 We'll say git clone this, and I'll just call this course,
0:43 and I'll put it on the desktop.
0:46 Okay, so you can see that appeared over here,
0:50 now we're going to create a folder in here called demos
0:55 and in the demos folder, this will be projects, so this is the project section.
0:59 So here is where I want to work, let's go over to PyCharm
1:03 and you can see when you're in PyCharm
1:05 it has the projects that you previously worked with,
1:08 this one is from the MongoDB course,
1:10 and we're going to create a new project.
1:12 Now, I'll do it this way first here, but in general,
1:16 I actually do a few steps on the command line before we get going
1:19 which I'll do in the next section here.
1:22 So we can start a brand new project
1:25 and we can come over here and say we're going to browse to it
1:28 and I want it in this location, in the demos, in the projects
1:34 and maybe we want to make a subdirectory here
1:36 because we might have more than just one.
1:38 So I'll call this first project.
1:41 Now notice, it's proposing that we use some kind of Python interpreter,
1:45 obviously that is required, but it turns out there are a lot of options,
1:49 here's a bunch of virtual environments that no longer are valid
1:52 I have to go back and clean that up,
1:54 I could even go over here and I could say
1:56 add a local alternative version that could be Python 3.6 that we have here
2:01 or it could be like PyPy, something like that,
2:03 I could even add a remote one over ssh or create a new virtual environment.
2:08 I'll just go with this one for now, the system default one
2:13 and this is going to create just a basic Python project,
2:17 it will be empty, we'll create files and so on.
2:19 If you want more structure, something that is not empty
2:21 we could go with Django, if we click here you'll see
2:24 it will actually give you all the settings to set up
2:27 the various templating languages and things like that,
2:30 or Flask, Pyramid, one of my favorites, you can pick
2:34 all the things that you might do from say
2:37 the cookiecutter template that comes from there,
2:39 there's a bunch of sort of frontend things down here as well, also Web2py.
2:42 But, we want to do this one, so let's say create
2:45 and notice it's going to run down here just for a second
2:49 and index all of the Python files in our main Python environment,
2:55 it also says, "Hey look, this is some kind of git repository,
2:59 would you like to add it?"
3:02 basically tell this project to understand the version control settings
3:06 that it found in the file structure, so yeah, we definitely want that.
3:10 So over here, we have no files in our projects,
3:13 and these external libraries, these are the various things installed in Python
3:17 this basically lets you look into the selected Python environment here.
3:23 So we're not going to worry about that right,
3:26 we can just basically ignore the external libraries.
3:28 We'll come up here and we'll say new,
3:32 and you can pick a whole bunch of different things here,
3:34 it could be an HTML file, it could be TypeScript
3:37 but we're going to go with Python.
3:40 In Python it will be, "Hello," maybe do a quick little, "Hello world,"
3:43 and notice, right away because we said yes
3:46 to understanding or incorporating that git hierarchy that it found,
3:50 it says we're going to automatically add this file,
3:52 do a git add on that file to our project.
3:56 You could say yes or no, I'll just say yeah, you always do that, that's fine,
4:00 and notice over here, that means it's green,
4:03 because it's now staged but not committed in git
4:06 so I'll just print, "Hello world," we'll talk about the editor a lot,
4:11 we're going to spend a whole chapter on that,
4:14 but for now, I really just want to focus on the files here,
4:17 if we had some other file just add some other file, other file, like that,
4:21 we could have a method, just print out something,
4:27 this is the other method, we'll come back to play with that in a little bit.
4:32 Notice, as I discussed in introduction,
4:35 down here we have the presentation assistant,
4:38 so mostly you'll see me working with hotkeys not menu items,
4:42 but that'll tell you what the hotkey was
4:45 as well as what the menu item would have been.
4:48 Okay, so now we have this project and we're pretty much ready to go,
4:51 we should be able to run it or something somehow.
4:54 But if you look over here, this whole little area
4:56 about running and debugging and testing and whatnot
4:59 it's all grayed out, it has no idea what to do with these files.
5:02 So the next thing that we need to do is
5:04 we need to say which of these files to run,
5:07 how to run it, what command line arguments to pass and so on.
5:10 So the way you do that is you right click on one,
5:12 you create what's called a run configuration
5:14 by picking one of these options down in this little area here,
5:17 so we'll say run, and it immediately runs down here,
5:22 it runs with the selected version of Python that we had
5:25 and it ran the file that is here in my desktop
5:30 and just here is the output, it said, "Hello world,"
5:34 or whatever it is that the script does,
5:38 and once you've done that, there's now what's called a run configuration
5:41 that lives up here and we can run it over and over,
5:44 we can run it with hotkeys, control r on Mac,
5:47 we can even debug into it, run it with coverage all those sorts of things.
5:51 So, that's how you create new projects in PyCharm.
