The factorial of a number is the multiplication result from 1 to the number. For example, the factorial of 5 is 1 * 2 * 3 * 4 * 5Write code that asks the user to enter a number and display its factorial. If the user enters 0, then display "Factorial value is 1". If the user enters a number greater than 0, then display its factorial value. For example, if the user enters 4, then display "Factorial value is 24"
Question
The factorial of a number is the multiplication result from 1 to the number. For example, the factorial of 5 is 1 * 2 * 3 * 4 * 5Write code that asks the user to enter a number and display its factorial. If the user enters 0, then display "Factorial value is 1". If the user enters a number greater than 0, then display its factorial value. For example, if the user enters 4, then display "Factorial value is 24"
Solution
Sure, here is a simple code snippet that accomplishes this:
# Ask the user to enter a number
num = int(input("Enter a number: "))
# Initialize the factorial value to 1
factorial = 1
# Check if the number is 0
if num == 0:
print("Factorial value is 1")
else:
# Calculate the factorial of the number
for i in range(1, num + 1):
factorial *= i
# Display the factorial value
print("Factorial value is", factorial)
This code first asks the user to input a number. If the number is 0, it directly prints "Factorial value is 1". If the number is greater than 0, it calculates the factorial by multiplying all numbers from 1 to the input number, and then prints the result.

Factorial of a Number Send Feedback You are given an integer ‘N’. You have to print the value of Factorial of ‘N’. The Factorial of a number ‘N’ is defined as the product of all numbers from 1 to ‘N’. For Example: Consider if ‘N’ = 4, the Factorial of 4 will be the product of all numbers from 1 to 4, which is 1 * 2 * 3 * 4 = 24. Hence, the answer is 24. Input Format: The test case contains one single integer ‘N’ representing the given integer. Output Format: Print the value of the factorial of ‘N’.
