def factorial(n):
    result = 1  # Initialize the factorial result to 1
    i = 1  # Start counter at 1
    while i <= n:  # Loop through numbers from 1 to n
        result *= i  # Multiply result by the current counter i
        i += 1  # Increment the counter
    return result  # Return the computed factorial

# Loop through numbers 1 to 10
num = 1  # Start counter at 1
while num <= 10:  # Loop until num reaches 10
    print(f"Factorial of {num} is {factorial(num)}")  # Print the factorial
    num += 1  # Increment counter

Answer by CoPilot AI:
Factorial Function

  • Function Definition: def factorial(n): defines a function named factorial that takes one parameter n.
  • Initialization: result = 1 initializes the variable result to 1, which will hold the final factorial value.
  • Loop: while i <= n: starts a loop that runs from 1 to n.
  • Multiplication: result *= i multiplies result by the current value of i.
  • Increment: i += 1 increments i by 1.
  • Return: return result returns the computed factorial value.

Loop to Print Factorials

  • Initialization: num = 1 initializes the variable num to 1.
  • Loop: while num <= 10: starts a loop that runs from 1 to 10.
  • Print: print(f"Factorial of {num} is {factorial(num)}") prints the factorial of num by calling the factorial function.
  • Increment: num += 1 increments num by 1.

Summary

  • The factorial function calculates the factorial of a given number n.
  • The second part of the code prints the factorials of numbers from 1 to 10.

I use YouTube when I get stuck and so try to find a tutorial channel that you enjoy learning from.
