Python program to find the factorial of a number provided by the user.

change the value for a different result

num = 7

To take input from the user

#num = int(input("Enter a number: "))

factorial = 1

check if the number is negative, positive or zero

if num < 0:
print(“Sorry, factorial does not exist for negative numbers”)
elif num == 0:
print(“The factorial of 0 is 1”)
else:
for i in range(1,num + 1):
factorial = factorial*i
print(“The factorial of”,num,“is”,factorial)

You missed the indentation!
Here is the code with correct indentation:

num = int(input("Enter a number: "))
factorial = 0
if num < 0:
    print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
    print("The factorial of 0 is 1")
else:
    for i in range(1, num + 1):
        factorial = factorial * i
        print("The factorial of," num, "is", factorial)

If this
print("The factorial of," num, "is", factorial)

is confusing then you can use format string which will be something like this:

print(f"The factorial of {num} is {factorial}")

Thanks
