Removing last line and initial whitespaces from an 8 by 8 list of integers in python

#Print the user board 

s = ''
for i in range(n):
    for j in range(n):
        z = i * n + j
        s += ' '
        if z < 10:
            s += ' '
        s += str(z)
    s += '\n'
print(dedent(s))

queens = list(map(int, input("Queens: ").split()))

I keep getting an error from my testcase environment of a last blank line before proceeding to the queens input below. What can I approach to fix

I have tried cleandoc from textwrap and while it works, it disrupts every required spacing and new distinctive lines for z from the "s" string which is a perfect 8 by 8 from 0 to 63.

>Solution :

Creating the right way instead of removing things after is easier:

from itertools import count
import toolz

n = 8
start_value = 0
counter = count(start_value)
rows = [" ".join(f"{num:2}" for num in toolz.take(n, counter)) for _ in range(n)]
print("\n".join(rows))
