Check if multiple strings exist in another string
I can't seem to find an equivalent of code that functions like this anywhere for Python:
Basically, I'd like to check a string for substrings contained in a list.

(1) First generate the possible sub-strings you want to search in each string. Is there a min or max length? Build a list or set of sub-strings from the input string. (2) Once you have the sub-strings to search for, try to identify the unique locations within the input string where the substrings appear.
Using String.contains() method for each substring. You can terminate the loop on the first match of the substring, or create a utility function that returns true if the specified string contains any of the substrings from the specified list.
To test if a string contains one of the substrings in a list in Python Pandas, we can use the str. contains method with a regex pattern to find all the matches.
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.
