You can also use the re (regular expression) module to search for
"hello" and make sure it's a complete word. You would use re to search
for something like "\bhello\b". "\b" being regex for an empty string
that only occurs at the start or beginning of a word.

More information on python regexes here: http://www.amk.ca/python/howto/regex/

Here is an example from that page:

>>> p = re.compile(r'\bclass\b')
>>> print p.search('no class at all')
<re.MatchObject instance at 80c8f28>
>>> print p.search('the declassified algorithm')
None
>>> print p.search('one subclass is')
None
