Member Functions

Member Functions Default Argument

While defining a methods we can assign some default values for its arguments.
Only arguments from right side can be assigned default values.
In case value is not provided in the function call default value is used.

Syntax:

def function-Name(self,argument,...,argument=value):
  Statements
  ----------
  return value
