Functions allow you to package a block of code to reuse it multiple times throughout the program, avoiding repetition and making the code more organized. During the lesson, we will create functions using `def`, understand the basic syntax, the use of parentheses, colons, indentation, and how to call a function to execute the code inside it. We will also see simple examples with welcome messages using print(), showing how a function can be called multiple times without needing to rewrite the entire code block.
