Python: Find a word within a string

I'm trying to find a word within a string with Python.

str1 = 'This string'
if 'is' in str1:
    print str1

In the above example I would want it to not print str1. While in the following example I would want it to print str2.

str2 = 'This is a string'
if 'is' in str2:
    print str2

How would I go about doing this in Python?

Use regex's word boundary also works

import re

if re.findall(r'\bis\b', str1):
    print str1

Split the string into words and search them:

if 'is' in str1.split(): # 'is' in ['This', 'string']
    print(str1) # never printed

if 'is' in str2.split(): # 'is' in ['This', 'is', 'a', 'string']
    print(str2) # printed
