The persistance is a the number of times the product of a number is carried out ex.
56 becomes 5*6 30 becomes 3*0 becomes 3 so the persistance is 2
53~~~15~~~~5

So how do i find the persistance of a number greater than 3 from 10-100 i know its 77, i have to make a program like this so i have

abc=False
per=0
for i in range (1,100):

if (i/10)*(i%10) > 9:
abc==True
per=1
if abc==True:
i/10 * i%10
per+=1
if per<3:
print i


but im not really getting anything like this. please give me some tips

Easy. Persistence of 56 is 1 + persistence of 30.
