Lære How to Create Functions in Python

Stryg for at vise menuen

When testing your code, you might assign different values to a variable to ensure it works correctly. However, as your codebase grows, this approach can become inefficient and cumbersome. A more effective solution is to use functions, which enhance flexibility and improve code organization. The general syntax for defining a function looks like this:

def function_name(parameter_a, parameter_b):
    # Function_body
    return # Return keyword with some value or without

To create a basic function that accepts two numbers, a and b, and returns the square of their sum, you can define a function that first calculates the sum of the two numbers and then squares the result. All lines within a function's body must maintain consistent indentation.


              123456
            
# Define function
def sum_squared(a, b):
    return (a + b) ** 2

# Call function
print(sum_squared(2, 3))
