Default arguments keyword arguments positional arguments arbitrary positional arguments arbitrary keyword arguments Default Arguments in Python Default arguments are values that are provided while defining functions The assignment operator is used to assign a default value to the argument The function parameter syntax is to indicate that some function parameters must be specified positionally and cannot be used as keyword arguments This is new in Python 3 8 It allows pure Python functions to fully emulate behaviors of existing C coded functions For example the built in pow function does not accept keyword arguments
