Python Functions and Modules Quiz

A User Defined Function is a function created by the user to perform a specific task, while a Built-in Function is a function that is already defined in Python and is readily available for use without the need for the user to define it.

Recursion is a technique in which a function calls itself in order to solve a problem. An example of recursion in Python is the Fibonacci sequence, where the nth term is the sum of (n-1)th and (n-2)th terms.

To create a user-defined module in Python, you simply create a Python file with a .py extension and define functions or variables in it. These functions or variables can then be imported and used in other Python programs.

<p>In Python, parameters are the variables listed inside the parentheses in the function definition, while arguments are the values passed to the function when it is called. For example, in the function 'def add(a, b)', 'a' and 'b' are parameters, and in the function call 'add(3, 5)', '3' and '5' are arguments.</p> Signup and view all the answers
