Determining if a string contains a word [duplicate]

Answer 1

You can also use regex:

\bblue\b will return True only if it can find the exact word 'blue', otherwise False.

In [24]: import re

In [25]: strs='blue yellow'

In [26]: bool(re.search(r'\bblue\b',strs))
Out[26]: True

In [27]: strs="nightly blues"

In [28]: bool(re.search(r'\bblue\b',strs))
Out[28]: False
