Python 3 crash course

[snippsat]

Are you using Windows?
The basic here Python 3.6/3.7 and pip installation under Windows.
If using PyCharm you most configure it to use Python 3, Configure a Python interpreter.

maybe i will try sublime text free version

A better option is VS Code from start

It's must that python and pip is configure right(on all OS Windows,Linux or Mac) from command line.

E:\div_code
λ python -V
Python 3.7.3

# look at code
