I have been working for about a week on a calculator in Tkinter, and the result is a very ugly, but functional calculator. Is it possible to clean up the code, and make it more readable?
from Tkinter import *
import tkMessageBox
import sys
import os
import math
main = Tk()
string = []
x = 'add'
def exit():
sys.exit()
def addNumberOne():
string.append(1.0)
Label(main, text = "1").grid(row = 0, column = 0)
def addNumberTwo():
string.append(2.0)
print '2'
Label(main, text = "2").grid(row = 0, column = 0)
def addNumberThree():
string.append(3.0)
print '3'
Label(main, text = "3").grid(row = 0, column = 0)
def addNumberFour():
string.append(4.0)
print '4'
Label(main, text = "4").grid(row = 0, column = 0)
def addNumberFive():
string.append(5.0)
print '5'
Label(main, text = "5").grid(row = 0, column = 0)
def addNumberSix():
string.append(6.0)
Label(main, text = "6").grid(row = 0, column = 0)
def addNumberSeven():
string.append(7.0)
print '7'
Label(main, text = "7").grid(row = 0, column = 0)
def addNumberEight():
string.append(8.0)
print '8'
Label(main, text = "8").grid(row = 0, column = 0)
def addNumberNine():
string.append(9.0)
print '9'
Label(main, text = "9").grid(row = 0, column = 0)

def enter():

answer.grid(row = 0, column = 3, columnspan = 30)

#Label(main, text = "%f"%(string[0] + string[1])).grid(row = 0, column = 3)

def restartAPI():

As you can see, it is fairly horrific, and as I am relatively new to Tkinter, I was wondering if there are some shortcuts or anything I can do to make it more readable?
