What is the usage of *args and **kwargs?

Answer»

In Python, we can pass a variable number of arguments to a function when we are unsure about how may arguments NEED to be passed to a function. These arguments can be passed using a special TYPE of symbols as depicted below.

  • *ARGS (Non-Keyword Arguments): This symbol is used in a function to pass a variable number of non-keyword arguments on which tuple operation can be performed. We use asterisk (*) symbol before the name of the parameter in ORDER to pass arguments of variable length.
  • **kwargs (Keyword Arguments): This symbol is used in a function to pass a variable number of keyword arguments dictionary on which dictionary operations can be performed We use double-asterisk (*) symbol before the name of the parameter in order to denote the argument type.

Function flexibility can be achieved by PASSING these two types of special symbols.
