Installing and "Hello World" Python 3 under OSX?

Question

Python

Hello! I liked the Python language with its philosophy and decided to get to know it better, but I found one unpleasant problem, in order to get to the "Hello World" moment on Python 3 on Mac, you need to spend a certain amount of time parsing the installation, I propose to "chew" this moment on this page for details:

I want to clarify right away: many, including me, did not manage to immediately get up to speed even from the third time in order to finally start writing code and finish installing the necessary tools for work.

1. Downloaded and installed the required distributions for OSX from https://www.python.org/downloads/ .
   
2. Installed PyCharm IDE.
   
3. Launched the PyCharm IDE, created a new project, created an index.py file.
   
4. I wrote the following code in the file:
   

a = 10
print a

I went into the browser and ran index.py, I got a = 10 print a.
Why didn't you get 10? Where is the error?
I'd appreciate the details, thanks!
