Python Naming Convention > Variable Naming

snake_case

  • Should be all in lowercase
  • Not begin with the special characters like e.g. & (ampersand), $ (dollar)
  • If the name contains multiple words, it should be separated by underscores (_) e.g. json_string
  • Avoid one-character variables e.g. a, b
class Student
    age = None
    ...

Private Variable

Python does not support privacy directly. This naming convention is used as a weak internal use indicator.

  • Should follow the above naming conventions
  • Should use a leading underscore (_) to distinguish between "public" and "private" variables
  • For more read the official python documentation.
class Student:
    age = None # public variable
    _id = 0 # Private variable
