[Tutor] For Loops Program Issue

[eric grunfeld]

Good Morning Everyone:

I am currently taking a beginners Python course that is being taught by
Google, on the Coursera platform.

I have been working on a problem but I seem to be obtaining an error
message after running the program.

Here is the problem:

def factorial(n):
    result = 1
    for i in range(result,n):
        result = result * n+1
    return result

print(factorial(4)) # should return 24
print(factorial(5)) # should return 120:

Here is the the error message that I have been receiving:

Here is your output:
85
781

Not quite. Pay attention at the operations that the code is
doing and make sure that the factorial function returns the
product of the numbers between 1 and n.

Based upon my understanding, it appears that my issue is with the set-up of
my range.

I look forward to any thoughts or comments that you may have.

All the best,
Eric
