Unable to enter if statement after raw_input

Whenever I call a function within a while loop in my project it will do absolute nothing according to the function just being called and will just continue to refresh the loop like nothing happened.

Here is a simple example I wrote demonstrating the problem. By running the code you will be shown a menu and you will need to enter a choice from the menu. When doing so a few "if" statements will check which option you chose and call and execute the code below them if the choice doesn't belong to any of the statements the menu will just refresh:

#!/usr/bin/env python

import os
import time

def test():
    x = True
    while True:
        if not x:
            print "You need to type 1\n"
        choice = raw_input("type 1 here: ")
        if choice == 1:
            print 'Works!\n'
            time.sleep(5)
            break
        else:
            x = False

def test2():
    print "Test123\n"

try:
    while True:
        os.system("clear")

        menu_choice = raw_input("Enter Choice: ")

        if menu_choice == 1:
            test()

        if menu_choice == 2:
            test2()

        if menu_choice == 3:
            os.system("python")

except:
    pass
