Explain this python code, how it results 7?

Question

def fact(x):
If x ==1:
return 2
else:
return x + fact(x - 1)
print(fact(3))

Answer 1

>>>fact(3)
>>>3 + fact(2) #3
>>>2 + fact(1) #2

x is now == 1 so...

2 #2

The sum of all the iterations (the numbers after the comments) is 7.

Answer 2

fact3 = 3 + fact2 = 3+2+fact1 = 3+2+2=7

Answer 3

Isaac Clarke what do you mean?
