Functions and Methods

The following convention should be followed for def naming:

• Avoid inbuilt names.
• snake_case or descriptive single word in lowercase should be used.
• function names should explain the functionality.
• for bound methods in class self should be used for first argument.
• for class methods in class cls should be used for first argument.
• decorators should be named in function convention.
