How can I check a string for substrings contained in a list, like in Check if a string contains an element from a list (of strings), but in Python?

Try this test:
any(substring in string for substring in substring_list)
It will return True if any of the substrings in substring_list is contained in string.
Note that there is a Python analogue of Marc Gravell's answer in the linked question:
from itertools import imap
any(imap(string.__contains__, substring_list))
In Python 3, you can use map directly instead:
any(map(string.__contains__, substring_list))
Probably the above version using a generator expression is more clear though.

@newtover: Generator expressions don't have square brackets.

is there any way to get the substring when it will return True?

@vagabond You can use
next(substring for substring in substring_list if substring in string), which will return the first matching substring, or throw StopIteration if there is no match. Or use a simple loop: for substring in substring_list: if substring in string: return substring.

@SvenMarnach variable 'substring''s lifetime is DONE and unavailable in the StopIteration exception
