1
00:00:00,230 --> 00:00:03,810
Sometimes you're going to want to see which Python packages

2
00:00:03,810 --> 00:00:04,800
you have installed.

3
00:00:04,800 --> 00:00:07,000
So there's a few different ways of doing this.

4
00:00:07,000 --> 00:00:09,200
There's the hard way which you could try.

5
00:00:09,200 --> 00:00:12,300
You could try to import the package from your Python shell.

6
00:00:12,600 --> 00:00:17,510
So you could do something like this, 'from colorama import *',

7
00:00:17,900 --> 00:00:20,420
everything. Okay. No complaints.

8
00:00:20,420 --> 00:00:21,600
But what if I did 'from

9
00:00:21,600 --> 00:00:27,100
packagethatclearlydoesnotexistonmycomputer

10
00:00:27,100 --> 00:00:30,200
import', anythingelse,

11
00:00:30,220 --> 00:00:34,950
a 'thing'. We're going to see, 'ModuleNotFoundError', and that

12
00:00:34,950 --> 00:00:37,400
this module, this package does not exist.

13
00:00:37,400 --> 00:00:38,840
So you could always try that.

14
00:00:38,840 --> 00:00:42,700
But you're really, you're guessing at that point, and that's no good.

15
00:00:42,700 --> 00:00:46,400
Now, a better way to live your life is to simply type 'pip

16
00:00:46,400 --> 00:00:50,150
freeze', and this actually isn't going to freeze anything.

17
00:00:50,540 --> 00:00:53,180
I'm sure there's a reason why they call it 'freeze', but it

18
00:00:53,190 --> 00:00:54,290
doesn't actually do anything.

19
00:00:54,300 --> 00:00:57,400
It just sort of takes a snapshot of all of your packages

20
00:00:57,400 --> 00:00:58,800
that are installed, and gives you a list.

21
00:00:58,830 --> 00:01:03,330
So when I hit 'Enter', you'll see a long list of all these different

22
00:01:03,330 --> 00:01:04,300
packages that I have.

23
00:01:04,300 --> 00:01:08,700
And I use pretty much all of these on a day to day basis,

24
00:01:08,700 --> 00:01:09,900
so I keep them.

25
00:01:09,900 --> 00:01:13,900
And if you're on a Unix like system, I'll show you a cooler shortcut here.

26
00:01:13,900 --> 00:01:15,930
This may or may not work on Windows, though.

27
00:01:15,930 --> 00:01:19,900
You can do 'pip freeze | grep',

28
00:01:21,300 --> 00:01:25,800
and then let's look for "colorama". "colorama", or just "color" even.

29
00:01:27,400 --> 00:01:28,800
So, we've got a package, 'colorama',

30
00:01:28,800 --> 00:01:30,800
the version is 0.4.3.

31
00:01:30,860 --> 00:01:35,240
Now, going back to this big list here, if you do a 'pip freeze'

32
00:01:35,250 --> 00:01:39,570
on your computer, and you don't necessarily recognize everything

33
00:01:39,570 --> 00:01:42,300
that's in there, that's actually okay.

34
00:01:42,320 --> 00:01:45,870
Chances are it was a dependency that was installed.

35
00:01:45,880 --> 00:01:48,450
So, like when I installed Django a couple of lessons ago,

36
00:01:48,450 --> 00:01:50,600
it comes with a few requirements.

37
00:01:50,670 --> 00:01:55,030
So let's do 'pip show Django', and it is 'Required-by: wagtail'.

38
00:01:55,030 --> 00:01:58,100
So if I did 'pip install wagtail' it would get Django for me,

39
00:01:58,100 --> 00:02:02,600
django-trebeard, django-taggit, and django-debug-toolbar.

40
00:02:02,600 --> 00:02:05,500
All of these packages require Django.

41
00:02:05,500 --> 00:02:08,900
So if I installed 'django-debug-toolbar, it might actually

42
00:02:08,900 --> 00:02:10,600
install Django for me as well.

43
00:02:10,630 --> 00:02:11,770
Let's do another one.

44
00:02:11,780 --> 00:02:13,270
'pip show requests'.

45
00:02:13,280 --> 00:02:17,040
This is a very popular package, and this one is required

46
00:02:17,040 --> 00:02:21,800
by requests-toolbelt, poetry, twine, PyVimeo,

47
00:02:21,880 --> 00:02:26,400
so the Python Vimeo API, which I've recently been using,

48
00:02:26,400 --> 00:02:28,300
and proxy-requests.

49
00:02:28,320 --> 00:02:33,490
And so if I installed PyVimeo, so I did 'pip install PyVimeo',

50
00:02:33,800 --> 00:02:36,800
it would also go ahead and get 'requests' for me as well.

51
00:02:36,820 --> 00:02:40,210
And that's why you might see a package in there that you

52
00:02:40,450 --> 00:02:45,020
don't necessarily know how it got in there. It's called a dependency,

53
00:02:45,020 --> 00:02:46,500
and so that's totally normal.

54
00:02:46,500 --> 00:02:47,900
