Functions

9. Functions

Functions are reusable blocks of code that perform a specific task.

Use def to create a function.

 def say_hello():

    print("Hello Robot!")



say_hello()

Functions can also receive information called parameters.

def greet(name):

    print("Hello", name)



greet("Clu-Bot")

Functions can return a result using return.

def add(a, b):

    return a + b



result = add(5, 3)



print(result)

Why use functions?

• Avoid repeating code.
• Organize your programs.
• Make programs easier to understand.
• Reuse instructions in different projects.
