You can use Regex.

Use word boundary (\b) to check for words, and $ to check for end of the line..

>>> line = "abc search"
>>> if re.search('(\\b(search)\\b)$', line):
          print "true"


true

>>> line1 = "search asdf"
>>> if re.search('(\\b(search)\\b)$', line):
          print "true"
>>> else:
          print "false"

false
