  fileName = fileName.rstrip('\n')
or just a plain:
  fileName = fileName.strip()

Not directly, since Python strings are immutable objects. If you want a
copy of the string without the last char *whatever it is*, you can just use
  somestr = somestr[0:-1]

But in your situation, it's usually safer to use [lr]?strip()

Here again, you cannot *remove* anything from a string - you can just
have a modified copy copy of the string. (NB : answer is just above :
use str.strip())
