Based off what I read in the pset description here, the highest columns of the pyramids should be only one # wide instead of two. So for an input of 5, the pyramid should be:

The problem is in spaces at the second half of pyramid. I have all strings of my output the same length. But check50 wants them to end right after the last # symbol.
