def factorial(n):
    # This function calculates the factorial of a non-negative integer.
    if n < 0:
        return "Factorial is not defined for negative numbers"
    elif n == 0:
        return 1
    else:
        # A more Pythonic way to write this could be using a ternary operator
        # or math.factorial, but this is a common implementation.
        result = 1
        for i in range(1, n + 1):
            result *= i
        return result
