How can you write a Python program to find the factorial of a number?

To find the factorial of a number in Python, you can use either an iterative or a recursive approach. The factorial of a number is the product of all positive integers from 1 to that number. For example, the factorial of 5 is

5×4×3×2×1

=120.

You can also use Python’s built-in library function:

Import the math module and use math.factorial().

Example: math.factorial(5) will return 120.
