How do you document a Python function?
Answer: You can document a Python function using docstrings, which are enclosed in triple quotes and provide information about the function's purpose, parameters, and return value.

What is a lambda function in Python?

How do you access a function's documentation?
Answer: You can access a function's documentation using the built-in "help()" function or by accessing the function's "doc" attribute.

What is function overloading in Python?
Answer: Unlike some other programming languages, Python does not support function overloading, where multiple functions can have the same name but different parameters.

Can a Python function return multiple data types?
Answer: Yes, a Python function can return multiple data types. The types can be specified using tuples, lists, or other data structures.

What is the purpose of the "pass" statement in a function?
Answer: The "pass" statement is a placeholder that does nothing. It is used when a statement is syntactically required but you want to do nothing.

Can you define a function inside another function in Python?
