Python Functions: Defining, Calling, and Using Parameters

A function is a named code block that performs a job or returns a value.
Functions are used to avoid copying code for repetitive tasks, and to divide a large program into smaller, more manageable parts.
Python has built-in functions and allows for user-defined functions.
A function definition includes the def keyword, function name, and parentheses to specify any necessary parameters, and always ends with a colon.
The function body includes the code to be executed, and can include a docstring to describe the function's purpose.
To use a function, it must be called by its name and any necessary arguments in parentheses.
Arguments are passed to a function as parameters, which are used as variables within the function body.
A function can return a value using the return statement, which can be assigned to a variable or used directly.
Functions can have multiple parameters, separated by commas, and must be passed the correct number of arguments.
Parameters and arguments are not interchangeable; parameters are defined in the function definition, while arguments are passed when calling the function.
User-defined functions can make code more readable, testable, and maintainable.
Functions can be used for a variety of tasks, from simple print statements to complex calculations and interactions with user input.
