The Ultimate Guide to Python Programming With Python 3.10 - def-Keyword

This video tutorial introduces the concept of functions in Python, explaining their purpose and how they can be created using the 'def' keyword. It covers the syntax for defining functions, including the use of parentheses and colons, and demonstrates how to call functions to execute their code blocks. The tutorial also delves into function arguments, distinguishing between positional and keyword arguments, and provides examples of how to pass and receive these arguments. The lesson concludes with encouragement to practice and revisit the material for better understanding.

What is the primary purpose of a function in programming?

• To manage memory allocation

• To create a user interface

• def

Why do we use parentheses when declaring a function?

• To differentiate it from a variable name

• To end the function declaration

• To specify the function's name

• To indicate a variable
