I just wrote my first Python program a guessing game and it exits with an error I get this.

[Armando Montes De Oca]

import random
import sys
enter = "Please Press Enter To Continue..."
print " Hello! Welcome to a Guessing game!"
print " Please Guess a number between 1 - 100"
computernum = random.randint (1, 100)
Guess1 = input ( "My First Guess Is:   ")
if Guess1 == computernum:
	print "You Win !"
	input (enter)
	sys.exit(0)
else:
	print "Sorry, Try Again!"
	print "You have Two guesses remaining!"
	Guess2 = input("My Second Guess Is:   ")
if Guess2 == computernum:
	print "Wow, Congradulations YOU WIN!"
	input (enter)
	sys.exit(0)
else:
	print "Sorry One more try!"
	print "You have One final guess remaining!"
	Guess3 = input (" My final guess is    ")
if Guess3 == computernum:
	print "Congradulations shit head"
	input (enter)
	sys.exit (0)
else:
	print "Sorry you loose the game."
	computernum = str(computernum)
	print "The computers number was!" + computernum
	input (enter)
	sys.exit(0)
