The first is the Pythonic method using the in keyword.,but keep in mind that this matches a sequence of characters, not necessarily a whole word - for example, 'word' in 'swordsmith' is True. If you only want to match whole words, you ought to use regular expressions: import re def findWholeWo, You could do: found = any(word in item for item in wordlist). It checks each word for a match and returns true if any are matches.,This function finds best matching substring of variable length. The implementation considers the corpus as one long string, hence avoiding your concerns with spaces and unseparated words. Code summary: 1.
