Create a Function to Calculate the Square of a Number

Write a Python function that takes a single number as input and returns its square. This is a fundamental exercise to practice defining functions and using arithmetic operators.

Challenge prompt

Build a function named square_number that accepts one parameter (a number) and returns the square of that number. For example, if the input is 4, the function should return 16.

Guidance

• Define a function using the def keyword.
• Use the parameter inside the function to perform multiplication.
• Return the result using the return statement.

Hints

• Remember that squaring a number means multiplying it by itself.
• If your function parameter is n, then the square is n * n.

Starter code

def square_number(n):
    # Your code here

Expected output

square_number(5) should return 25 square_number(10) should return 100
