print the correct output but keep getting 'invalid literal found' error. what a stupid exercise.

There are a BUNCH of hidden constraints on this problem:

 - only 1x for loop
 - only cant use str()
 - only 2x lines of code (is actualy in the description ... but not very well)

This question should be re-written, retired, or moved to a code-golf section

for i in range(1,int(input())+1):
    print(*range(1, i), *range(i, 0, -1), sep="")

Asked for one print statment Asked for on for loop

I'm this close to loosing it with hackerank

for i in range(1,int(input())+1):
    print(*range(1, i), *range(i, 0, -1), sep="")

Asked for one print statment Asked for on for loop

I'm this close to loosing it with hackerank

this is my solution:

for i in range(1,int(input())+1): print((111111111//10**(9-i))**2)
