Thanks to sepp2k and Dogstopper, I have surpassed the previous error however I am greeted with a new one.

Traceback (most recent call last):
  File "/home/k3y/Python/Look2.py", line 37, in <module>
    main()
  File "/home/k3y/Python/Look2.py", line 22, in main
    uName.append((first[0] + last[:(len(last)/2)]))
TypeError: slice indices must be integers or None or have an __index__ method

In Python 3 the division operator / returns a floating point number even if both operands are integers. So you can't use the result of / as an array index. Instead you should use the integer division operator //.

Thank you sir; I believe that I finally got it ( I feel proud ):

#!/usr/bin/python3

    elif check != 'n' or 'N':
        output = input('\nWhat should the name of the file be, containing the username(s) be? ')
        out = open(output)

it may not pass a professionals standard but I think for one of my first true script redos it is pretty snappy =D.
