When you're looking at your code,
0:01
one of the really, really powerful things that PyCharm does for you is understand
0:05
how the files fit together, how maybe this rps,
0:09
rock paper scissors game is using the shared lib 'ui_helper' right there and not just
0:17
one or two files, but many,
0:18
many files as I've said before,
0:21
But if you forget where to go to find out exactly what this is.
0:25
Again, this is a pretty simple example,
0:27
but think 20, 30 thousand lines of python,
0:30
maybe it's a new project you just picked up.
0:32
Where is this, where is this coming from?
0:34
Is this uh package they've installed?
0:37
Is this another file, a module?
0:39
Uh sub module in this application,
0:41
something like that. So there's a lot of cool things you can do.
0:44
One option would be to go over here.
0:45
So I want to know where this header is.
0:48
I can go to navigate and there's all sorts of cool stuff going on click implementation
0:54
or declaration and it's going to take us over here or is this navigate via command+v
1:00
So now I don't have to use that awkward.
1:03
UI I can just come over here and command B and it'll take me
1:06
here like Okay, great. Now I see where this header is coming from,
1:09
right. This is a file that I've created and it's this is a little breadcrumb
1:13
navigation bit to where the file is and you can actually navigate with these things as
1:17
well, like you can go between these these pieces.
1:20
So that's really cool. But what I prefer is on Mac to hold down command
1:26
and on Windows or Linux hold down control.
1:29
And then as you move around,
1:31
notice everything becomes a hyperlink. Random is a hyperlink,
1:35
notice it knows the file name,
1:37
even here's the UI helper, here's the library,
1:41
this header. If I click on this,
1:43
it takes me over there so cool and down here we have this random choice,
1:48
it's going to take us down well inside a Random,
1:50
not super helpful, but it does take us there to show its inside the random
1:53
package. Get role. Where is that?
1:55
I don't know. Oh there it is.
1:57
Take this down here, right?
1:58
So if we just hold down command or control all of a sudden everything everything here
2:03
like even where is this player to find?
2:06
Oh it's a parameter as opposed to say a global variable,
2:10
which could have also been used in exactly the same way.
2:13
So I strongly recommend that you cruise around your code using command. It's really really nice.
