State whether the following statements are True or False:

1. A function cannot be defined without parameters.
2. The return statement without parameter indicates a non-returnable function.
3. A function can return only one value to its caller program.
4. The parameters used in the function definition are called actual parameters.
5. A function may or may not return a value to the main program.
6. A function always contains the header and the footer.

1. False
   Corrected Statement: A function can be defined without parameters. An empty parameter list simply indicates that the function doesn't receive any value during its call.
2. True
3. False
   Corrected Statement: Unlike other programming languages, Python can return more than one value or multiple values from a function to its caller.
4. False
   Corrected Statement: The parameters used in the function definition are called formal parameters, not actual parameters. The values passed to the function during its call are called actual parameters (or arguments).
5. True
6. False
   Corrected Statement: A function always contains the header and the body, not the footer. A function consists of a function header and a function body.
