Python string filtering

stringFilter.py

import re

FILTER_WORDS = ["spam", "morespam", "blahblah"] # and so forth

FILTER = re.compile("|".join(FILTER_WORDS))

def phrasePassesFilter(word):
	'''Checks if the phrase passes the filter'''
	return not bool(FILTER.match(word)) # if there are no matches, FILTER.match --> None, so it passes the filter
	# otherwise, it's True so it contains a filtered word, so mark as spam

def isSpam(word):
	'''Same as above, but just checks if spam and not if it passes the filter'''
	return bool(FILTER.match(word))
	
print isSpam("my spam is so sneaky") # --> True
print phrasePassesFilter("my spam is so sneaky") # --> False

print isSpam("rushy") # --> False
print phrasePassesFilter("rushy") # --> True
