Python Factorial Calculation: A Complete Code Example

The given code is incomplete and does not specify what needs to be done. However, based on the provided code, it seems that the goal is to calculate the factorial of a given number.

Here's an updated version of the code that calculates the factorial of the given number:

def TEST_DO_NOT_CHANGE(num):
    print(num)
    factorial = 1
    for i in range(1, num + 1):
        factorial *= i
    return factorial

if __name__ == '__main__':
    print(TEST_DO_NOT_CHANGE(38))
    print(TEST_DO_NOT_CHANGE(1))

This code uses a for loop to iterate from 1 to the given number and multiplies each number to the 'factorial' variable. Finally, it returns the calculated factorial.

Note: The code provided above assumes that the given number 'num' is a positive integer.
