print(10**i//9*i)

Use this ,It will clear the test - First make all the multplier to 1 then multiply it by i.

why isn't this allowed?

for i in range (int(input())-1): print (int(format (2**(i+1)-1,'b'))*(i+1))

edit: ok this is dumb but i think its because of the 'for' in 'format'. Can the dev pls patch this?

if i use the following instead, it works: for i in range (int(input())-1): print (int(bin (2**(i+1)-1)[2:])*(i+1))

For Python3 Platform

for i in range(1,int(input())):
    print(i * (10**i)//9)

for i in range(1,int(input())): #More than 2 lines will result in 0 score. Do not leave a blank line also print(i*sum(list(10**(j) for j in range(i))))

this gives only 1 for is allowed. Even though this solves the problem.
