If statement [Guard List]

[yuvalsaias]

hello everyone, im a  soldier and in my unit there is a lot of guard duty which means that everyday each soldier have a 3 hours guard duty which he takes care of an a specific area.
there is a specific guy which makes the list of the guards keeping time and what im trying to make is a program which make that list automatic without a man manualy making it.
there is 2 areas that sometimes your guard there sometimes there so here is what i made for now :

from random import *
guards = [] #here there is the names of all the available guards!
newguards = []
guardscount = input('How many guards guard?:')
for i in range(0,int(guardscount)):
   i = input('What is the guard name:?')
   guards.append(i)

guardians = {}
times = ['23:00-2:00','00:00-03:00','02:00-05:00','03:00-06:00','05:00-08:00','06:00-09:00','08:00:11:00','09:00-12:00',
         '11:00-14:00','12:00-15:00','14:00-17:00','15:00-18:00','17:00-20:00','18:00-21:00','20:00-23:00','21:00-00:00']
day = 21
month = 3
index = 15
while day < 23:
   for x in guards:
       guardians[x] = times[randint(0, index)]
       times.remove(guardians[x])
       index -= 1
       if index == 0 :
           print('Today', day, '/', month, 'This is the Guardians List:', guardians)
           times = ['23:00-2:00','00:00-03:00','02:00-05:00','03:00-06:00','05:00-08:00','06:00-09:00','08:00:11:00','09:00-12:00',
                        '11:00-14:00','12:00-15:00','14:00-17:00','15:00-18:00','17:00-20:00','18:00-21:00','20:00-23:00','21:00-00:00']
           index = 15
           day += 1

   if len(guards) == 0:
       guards = newguards
       newguards = []
       continue

the problem i have here is that somehow the if index =0 statment apply even when index is not 0 i dont know why..

sorry about my english...its not my home language so..
