Understanding functions and procedures is very important for anyone who wants to be a programmer. This is especially true for Year 9 students who are just starting to learn the basics of programming. Functions and procedures help make your code less complicated, which means it is easier to read and can be used again in different places. Let’s look at their benefits and see some examples.
Functions are parts of code that do a specific job. They take some information, work on it, and then give you a result back. For example, a function that calculates the area of a rectangle looks like this:
def calculate_area(width, height):
return width * height
In this example, calculate_area takes two pieces of information (width and height) and gives back the area.
Procedures, on the other hand, are similar but don’t give you a final result. They do things like print messages or change values. For example:
def print_greeting(name):
print("Hello, " + name + "!")
Breaking your program into functions and procedures helps you handle bigger projects. Instead of writing one big piece of code, you create smaller parts that are easier to manage. This way, if there’s a mistake, you can find it more easily because you know which function to check.
Once you create a function, you can use it many times in your program. For example, if you made a function for calculating area, you can use it with different sizes without having to rewrite it:
area1 = calculate_area(5, 10)
area2 = calculate_area(3, 7)
Functions and procedures make your code easier to read. If someone looks at your code, they will find it simpler to understand what is happening. For example, instead of seeing a confusing line like result = width * height, you will see result = calculate_area(width, height), which is much clearer.
As you start working on your programming projects, remember that learning about functions and procedures is not just about knowing how to write them. It’s also about how to think like a programmer. By using functions and procedures, you are preparing yourself for success in programming.
Whether you are working on small projects or helping out with bigger ones, knowing these ideas will make your programming much easier and more fun. So, as you keep learning, make sure to use the power of functions and procedures!
