Learning Python – Coding Style

Check out my new course Learn you some Lambda best practice for great good! and learn the best practices for performance, cost, security, resilience, observability and scalability.

  • Use 4-space indentation, no tabs

 

  • Wrap lines so that they don’t exceed 79 characters

 

  • Use blank lines to separate functions and classes, and larger blocks of code inside functions

 

  • When possible, put comments on a line of their own

 

  • Use docstrings

 

  • Use spaces around operators and after commas

 

  • Name your classes and functions consistently; the convention is to use CamelCase for classes and lower_case_with_underscores for functions and methods

 

  • Always use self as the name for the first method argument

 

  • Don’t use fancy encodings if your code is meant to be used in international environments

    Naming conventions:

    Variables / functions – use_lower_case_separated_by_underscore

    Class names – UseCamelCase

    Error classes end in Error, i.e. MyError
