Python Exercise 2 – Factorial of a Given Number Using Function

Python Exercise 2 Problem

In this Python exercise, write a Python program that will compute the factorial of a given number. The given number is entered with the user input between 1 and 10. Also, the result of this Python program should result with a print on a single line.

Note: This exercise is completed in Python 3.7

Python Exercise 2 Solution

Python Code Input:

num = int(input("\nEnter a number between 1 and 10: "))
try:
   x = int(num)
   print(f"\nThe number entered is {x}.")
except ValueError:
   print(f"\nIn order to convert a number to an integer, the value entered must be a number. You entered {num} .")
def fact(x):
    if x == 0:
      return 1
    return x * fact(x - 1)
print(f"\nThe result of {x} * fact({x} - 1) is", (fact(x)))

User Input:

Enter a number between 1 and 10: 5

Python Code Output:

The number entered is 5.
The result of 5 * fact(5 - 1) is 120
