Python Basic Calculator

#!/usr/bin/python

# PyCalc, a small Pyhton calculator.
# Verison 0.3x
# Created by Ceil
# Created on May 15, 2017 @ 10:30pm
# Performs basic math functions (add, subtract, multiply, divide).
 # Does NOT support direct equations in the text bar... yet ;)
 # This is my first GUI Python application so feel free to shoot me any pofloaters!
 # Code is open source.
