word search

[Aloysio Figueiredo]

I think you will have to use regular expressions. Fortunately, in 
your particular case the regular expression is not a very complicated
one...

=======================================
import re

p = re.compile('.*[^a-zA-Z0-9]cow[^a-zA-Z0-9].*', re.IGNORECASE)

test = ' cow ', '_cow_', '(cow)',' -cow, ', '_cOw-', 'coward'

for t in test:
  if p.match(t):
    print '"cow" is in "%s"' % t
  else:
    print '"cow" is _NOT_ in "%s"' % t

=======================================

result:

"cow" is in " cow "
"cow" is in "_cow_"
"cow" is in "(cow)"
"cow" is in " -cow, "
"cow" is in "_cOw-"
"cow" is _NOT_ in "coward"
