I read the question as "I've got this function and it does what I expect
but I don't understand the code".
On that basis...
The function creates a factorialfor the input number 'n' (i.e.
1*2*3*4.....*n)
The first 2 lines checks to see that the input is less than 2 and, if
so, returns a value of 1
The rest of the code counts down from n to 1 multiplying f by n at each
iteration.
If I guessed the right question, reply to the post for further
clarification.

Hi!
Since there is no stated question, I need to guess:
n -= 1 (instead of "f -= 1")
should work.
Or maybe the question was a totally different one...

def factorial(n):
if n<2:
return 1
f = 1
while n>= 2:
f *= n
f -= 1
return f
please it works.but don’t get why the return 1 and the code below.
