using underscore in python

All programming languages do have some common elements; inputs, functions, outputs, variables, ... . But there are also unique idea in some programming languages and if you want to know about them, you need to specifically study them. This is what makes a person proficient in a specific programming language.

One of these is the usage of underscore ( the _ ) in Python programming. In this video I will show you 7 different usages of this character from a very trivial "digit separator" to a more cool "underscore as a dummy variable" and some more advanced topics like the meaning of name == "main" which you might see in some source codes (and most of the libraries).

Lets start and let's write better code!
