You should use re.search here not re.match.

From the docs on re.match:

If you want to locate a match anywhere in string, use search() instead.

If you're looking for the exact word 'Not Ok' then use \b word boundaries, otherwise if you're only looking for a substring 'Not Ok' then use simple : if 'Not Ok' in string.

>>> strs = 'Test result 1: Not Ok -31.08'
>>> re.search(r'\bNot Ok\b',strs).group(0)
'Not Ok'
>>> match = re.search(r'\bNot Ok\b',strs)
>>> if match:
...     print "Found"
... else:
...     print "Not Found"
...     
Found
