Filter list of strings using list comprehension

Question

>>> li = [\"a b self\", \"mpilgrim\", \"foo c\", \"b\", \"c\", \"b\", \"d\", \"d\"]
>>> condition = [\"b\", \"c\", \"d\"]
>>> [elem for el         


        

Answer 1

Assuming the code needs to retrieve all the strings that contain any of the conditions strings:

[elem for elem in li if any(c in elem for c in condition)]

In case a full match of a condition is required:

[elem for elem in li if
 any(re.search('(^|\s){}(\s|$)'.format(c), elem) for c in condition)]

Edit: This can be simplified to a single pre-defined regex:

predicate = re.compile('(^|\s)({})(\s|$)'.format('|'.join(condition)))

[elem for elem in li if predicate.search(elem)]
