Welcome back to iview Tech Hub Day 15. Today you'll learn one of the most powerful ideas in programming functions. Imagine writing the same code again and again. Annoying, right? Functions let us write code once and reuse it whenever we want. Functions help programmers save time, stay organized, and build real applications. They are the building blocks of professional software. A function is a named block of code that performs a task. We define it using the keyword def. The def keyword. Hell's Python. We are creating a function. It's followed by a unique name. Nothing runs until we call the function. Calling means telling Python to execute the code inside. Just type the name followed by parentheses. Python will then jump to your code and run it. Parameters let functions receive information. This makes your code dynamic and reusable for different inputs. The return keyword sends a value back. This is how functions help in calculations and data processing. See how ad 5. Three returns 8. This allows us to use the results elsewhere in our program. Pause the video and try create a function that prints your school name and another that adds 2 numbers. You're thinking like a programmer now. Keep practicing and I'll see you in the next lesson. Happy coding.
