Alright, you have now discovered all the most
important programming fundamentals with Python.
With this knowledge, you will be able to create almost any project you want.
Now is the time to go to the last level of this course,
and this is a little bit different than the first three levels.
Working with variables, lists, functions,
conditions, loops, etc. is the first fundamental
step you need to take to learn Python, and that's what you have just done.
Now we are going to increase the scope of what you can do with your programs.
The true value you will get from your program
is when you start to make it interact with the
outside, and when you use the environment of
your computer along with your Python code.
So in the following lessons, you will learn how to read from a file
and write to a file on your computer with Python.
You will learn how to use the built-in Python modules
and how to run Python programs directly from the terminal.
At the end of this section, you will be able to work
with the environment around your Python programs.
Make sure you're okay with all the first three sections.
That's very important so you can understand the following.
If needed, come back to a few previous lessons before you start this section.
Alright, and now let's get started.
