- Description: Formal arguments are the parameters listed in the function definition that define how inputs are passed into the function.
- Positional arguments: It refers to how actual arguments are matched with formal arguments in a function based on their order of appearance.
- Keyword arguments: It passing arguments to a function using their names (keywords) instead of relying solely on their position in the function call.
- Variable-length arguments: It allows functions to accept an arbitrary number of arguments, which can be either positional or keyword arguments.
- Arbitrary Positional Arguments(*args): Allows a function to accept any number of positional arguments.These arguments are collected into a tuple.
- Arbitrary Keyword Arguments(**kwargs): Allows a function to accept any number of keyword arguments.These arguments are collected into a dictionary.
