Python Not Exiting Tic Tac Toe Game

I have an extremely basic tic tac toe game in python. For some reason, the game does not quit when the user enters "e". Why is this?

import os
import sys
os.system("cls")

one = "1"
two = "2"
three = "3"
four = "4"
five = "5"
six = "6"
seven = "7"
eight = "8"
nine = "9"
selection = ""

def instructions():
    print("""
Welcome to Tic-Tac-Toe!
To Play, Enter a number between 1-9 to select that space
""")

def board():
    print("\t{} | {} | {}\n\t---------\n\t{} | {} | {}\n\t---------\n\t{} | {} | {}".format(one,two,three,four,five,six,seven,eight,nine))
    selection = input("\nSelect a number:\n")
    os.system("cls")

instructions()

while selection != "e":
    board()

For a simple reason that the selection variable in the board and the one checked outside is not the same.

The quick fix would be to add 

global selection

at the start of the function board. You should consider reading about scopes of variables in Python.

The final code will be

def board():
    global selection
    print("\t{} | {} | {}\n\t---------\n\t{} | {} | {}\n\t---------\n\t{} | {} | {}".format(one,two,three,four,five,six,seven,eight,nine))
    selection = input("\nSelect a number:\n")
    os.system("cls")
