This is because AND operator short-circuits. So when 1 < foo() is false, it

Python widespread adoption is better idea. It's good to have a newer version
arrive after a gap, so we can play catchup game. I hadn't still migrated to

The thought which comes to my mind is Modular exponentiation :
for a ** b % r ( if a ** b very large )
I had coded it in C++ but in python the pow() have inbuilt modular-function
made.
so pow(a ,b, r) does the trick
Here for factorial :
F(n) = n * n-1 * n-2 ...* 2 * 1
