Well, another way of doing it would be

 >>> values = "this is a test"
 >>> chars = "aeiou"
 >>> "".join([c for c in values if c not in chars])
'ths s  tst'

If your either your chars is a large set or you're performing 
this repeatedly with the same set of chars, you might want the 
speed of membership-testing that one would get from a true set:

 >>> charset = set(chars) # do this once for the set
 >>> # do the following as many times as you like in loops, etc.
 >>> "".join([c for c in values if c not in charset])
'ths s  tst'
