Search or compai problem

[Gallagher, Tim (NE)]

I am new to python and I want to compare 2 strings, here is my code:
[start]

import active_directory
import re

lstUsers = []
users = active_directory.root()
for user in users.search ("sn='gallagher'"):
    lstUsers.append(user.samAccountName)
        
print "----------------------------------------"
lstUsers.sort()

## Printing out what is inside of the arrar(list)
x = 0
while x < len(lstUsers):
    if re.compile(lstUsers[x]).match("None",0):
        print "Somthing here"
    
    x = x + 1

[/end]

When I do the:
    if re.compile(lstUsers[x]).match("None",0):
        print "Somthing here"

Some of the items in lstUsers[x] are the word None.  I am not sure why I
cant do this 

I want to compare lstUsers[x] to the word "None", how can I do this.
Thanks
