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*(10*i-1)//9)

This works for me:

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

it is important delete all comments because the judge count every line

I didn't figure out the math but found a way of using the walruss operator:

for i in range(1,int(input())):
    print( i * (prev := (1 if i == 1 else prev + pow(10, i - 1) ) ) )

The normal solution

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

The Abnormal Solution

for i in range(1,int(input())):
    print([1, 22, 333, 4444, 55555, 666666, 7777777, 88888888, 999999999][i-1])
