1
00:00:00,000 --> 00:00:02,434
Alright, you have now
discovered all the most

2
00:00:02,446 --> 00:00:05,000
important programming
fundamentals with Python.

3
00:00:05,001 --> 00:00:10,000
With this knowledge, you will be able
to create almost any project you want.

4
00:00:10,001 --> 00:00:12,000
Now is the time to go to
the last level of this course,

5
00:00:12,001 --> 00:00:16,000
and this is a little bit different
than the first three levels.

6
00:00:16,001 --> 00:00:19,674
Working with
variables, lists, functions,

7
00:00:19,686 --> 00:00:24,000
conditions, loops, etc.
is the first fundamental

8
00:00:24,001 --> 00:00:28,000
step you need to take to learn Python,
and that's what you have just done.

9
00:00:28,001 --> 00:00:33,000
Now we are going to increase the scope
of what you can do with your programs.

10
00:00:33,001 --> 00:00:34,967
The true value you will
get from your program

11
00:00:34,979 --> 00:00:37,000
is when you start to
make it interact with the

12
00:00:37,001 --> 00:00:40,058
outside, and when you
use the environment of

13
00:00:40,070 --> 00:00:43,000
your computer along
with your Python code.

14
00:00:43,001 --> 00:00:48,000
So in the following lessons, you
will learn how to read from a file

15
00:00:48,001 --> 00:00:51,000
and write to a file on
your computer with Python.

16
00:00:51,001 --> 00:00:54,000
You will learn how to use
the built-in Python modules

17
00:00:54,001 --> 00:00:59,000
and how to run Python
programs directly from the terminal.

18
00:00:59,001 --> 00:01:02,078
At the end of this section,
you will be able to work

19
00:01:02,090 --> 00:01:05,000
with the environment
around your Python programs.

20
00:01:05,001 --> 00:01:08,000
Make sure you're okay with
all the first three sections.

21
00:01:08,001 --> 00:01:12,000
That's very important so you
can understand the following.

22
00:01:12,001 --> 00:01:17,000
If needed, come back to a few previous
lessons before you start this section.

23
00:01:17,001 --> 00:01:19,000
Alright, and now let's get started.
