Add comments to your code

[sondosmohsen]

Add comments and docstrings to your code to explain the purpose of each section, function, and variable.

Provide explanations or markdown cells to describe the datasets, the structure of the dataframes, and the visualization techniques used.

@sondosmohsen Text/explanations to the nb will be added as suggested in your first comment. Regarding your second comment and the addition of docstring/comments, is this for all *.py routines?
