pyflakes VS mccabe

Pyflakes is a simple program that checks Python source files for errors. It is similar to PyLint but focuses only on errors, not style. This makes it faster and less intrusive than some other tools.

PyFlakes—another bug checker (it only checks for logical errors, not for style, but it works faster);

Cyclomatic Complexity is a metric used to determine the stability of your code. It basically boils down to the more code you have the more problems that can arise in said code. There are even modules for python to check your cyclomatic complexity. It goes hand in hand with separating your code out into modules. I work for a FAANG company and we usually want to keep our cyclomatic complexity less than 10 with that tool above.

A more advanced best practice would be separating different functions of your code into different files to keep Cyclomatic Complexity low. More code usually = more problems can be in said code. There’s even a tool you can use to determine how complex your code is called mccabe. Lower is better with that
