def factorial(x): total = 1 for x in range(1,x+1): total *= x return total This is my solution, I used an example from another user but I don't understand why you have to set total = 1 or why the range is configured as it is. How does this affect the result?
Well, if you multiply something with
1, it stays the same, and you need a start value, so
1 is perfect
why not? You want all the numbers from 1 till
x is not included (it is lesser then x) so you have to add
+1 so that
x is also included
AH ! Thank you, this really clarified everything :]
still, you learn far less from this then actually write a solution yourself. It is like reading math solutions, and then at the exam you have a problem
