To find factorial in python

#1

how did no=10 ans=1 for i in range(1,11):
ans *= i give the factorial ?

#2

Initially value in ans=1
Due to for loop I will take value 1,2,3,4,5,6,7,8,9 and 10 .
So initially the value of I will also be 1 and it will keep on increasing .
So for the first iteration ans = ans1 = 11 =1
For second iteration i will become 2 ,so ans=ans2 =12=2
Now the value of ans=2
For the next iteration i=3 , so ans= ans3=23 =6
Now ans=6
For next iteration i=4 , ans= 6*4= 24
This will keep on occuring till i become 10
