00:00:06,313 --> 00:00:09,340
- Welcome to the Before You Begin lesson.

2
00:00:09,340 --> 00:00:12,070
In this lesson, I'm going
to help you get setup

3
00:00:12,070 --> 00:00:14,346
to work with these LiveLessons videos.

4
00:00:14,346 --> 00:00:16,880
First off, we'll talk about how to acquire

5
00:00:16,880 --> 00:00:21,100
the code examples that you'll
want to run in parallel

6
00:00:21,100 --> 00:00:22,686
with watching the videos.

7
00:00:22,686 --> 00:00:25,650
Next up, we'll go ahead
and talk about installing

8
00:00:25,650 --> 00:00:28,320
the Anaconda Python distribution

9
00:00:28,320 --> 00:00:30,160
and one of the nice things about this

10
00:00:30,160 --> 00:00:31,010
is first of all,

11
00:00:31,010 --> 00:00:34,530
it's available for macOS,
Windows, and Linux,

12
00:00:34,530 --> 00:00:37,785
and it's super easy to install
on all three platforms.

13
00:00:37,785 --> 00:00:41,553
But it also comes with a ton of popular

14
00:00:41,553 --> 00:00:43,971
Python opensource libraries.

15
00:00:43,971 --> 00:00:46,347
So you're often going to be able

16
00:00:46,347 --> 00:00:48,890
to work with those
libraries without having

17
00:00:48,890 --> 00:00:50,970
to install them separately.

18
00:00:50,970 --> 00:00:53,600
We will, of course, install
some additional libraries

19
00:00:53,600 --> 00:00:56,090
throughout these
LiveLessons videos as well.

20
00:00:56,090 --> 00:00:59,950
But we'll talk about the two
different package managers,

21
00:00:59,950 --> 00:01:02,920
which you'll use for installing
those other libraries.

22
00:01:02,920 --> 00:01:04,229
One of them is called Conda,

23
00:01:04,229 --> 00:01:05,840
which is part of the Andaconda,

24
00:01:05,840 --> 00:01:07,298
and one of them's called Pip.

25
00:01:07,298 --> 00:01:11,760
And both of them can be
used to install packages

26
00:01:11,760 --> 00:01:13,918
into your Python system.

27
00:01:13,918 --> 00:01:17,610
We'll also talk about installing
some additional software

28
00:01:17,610 --> 00:01:20,744
that will help you run
some of the animations

29
00:01:20,744 --> 00:01:23,919
that we provide in the
context of what are known

30
00:01:23,919 --> 00:01:26,200
as Jupyter Notebooks.

31
00:01:26,200 --> 00:01:29,963
Jupyter Notebooks is a great
way to work with Python,

32
00:01:29,963 --> 00:01:34,963
allows you to combine
text, audio, video, images,

33
00:01:35,240 --> 00:01:39,395
and live executable code
into a web-based document

34
00:01:39,395 --> 00:01:42,459
and it's really the preferred way nowadays

35
00:01:42,459 --> 00:01:47,459
to provide people with the
results of a data science study

36
00:01:48,470 --> 00:01:49,999
or other scientific study

37
00:01:49,999 --> 00:01:54,760
in a manner that they can
reproduce those results as well.

38
00:01:54,760 --> 00:01:57,500
So I do encourage you to take a look,

39
00:01:57,500 --> 00:01:59,338
especially as you go into lesson one,

40
00:01:59,338 --> 00:02:01,895
at the test drive of Jupyter Notebooks,

41
00:02:01,895 --> 00:02:04,475
to become familiar with that interface.

42
00:02:04,475 --> 00:02:07,017
I think you'll find it
to be a preferred way

43
00:02:07,017 --> 00:02:09,899
to use and interact with Python.

44
00:02:09,899 --> 00:02:12,490
We'll also talk about getting yourself

45
00:02:12,490 --> 00:02:14,760
a Twitter Developer Account for use

46
00:02:14,760 --> 00:02:16,746
in some of the later lessons

47
00:02:16,746 --> 00:02:19,773
and finally, I'll provide you
with my contact information

48
00:02:19,773 --> 00:02:21,580
in case you have any questions

49
00:02:21,580 --> 00:02:23,663
while you're watching the videos.
