xsize = int(input('square hash dimension: '))
def square():
    i=0
    while i < xsize:
        x = '#'*xsize  
        print(x)       
        i+=1

print(square())

// trying to write a couple lines to recreate the dimensions input to make a square out of hashes, but the result when -say, 2 is input as 'xsize': (imgur link) output from code

not sure why 'none' is being added, but i am quite new to programming on the whole :P ty in advance!

you aren't returning anything from the function, so when you call `print(function())` if the function doesn't have anything to return it returns None and you print that. – MooingRawr Jan 05 '17 at 18:00

you don't return anything – Yevhen Kuzmovych Jan 05 '17 at 18:00
More specifically, python is implicitly returning `None` for you. – MrAlexBailey Jan 05 '17 at 18:01
how should i write the return in? – georgiewot Jan 05 '17 at 18:01
python functions return none by default if you don't return anything explicitly – RustyShackleford Jan 05 '17 at 18:01

you don't _want_ to return anything. just call `square()`. Don't print return value, useless. – Jean-François Fabre Jan 05 '17 at 18:02
