Find a close match of a word / string

Now, about some obscure features in the Python standard library. If you find that you need to use something like Levenshtein distance [2] to find similar words in the input string, then Python's difflib will support you.

Import difflib difflib.get_close_matches ('appel', [' ape', 'apple',' peach', 'puppy'], nasty 2) # returns [' apple', 'ape']

Difflib.get_close_matches will look for the best "good enough" match. In this case, the first parameter matches the second parameter. We can also provide an optional parameter n, which specifies the maximum number of matching results to be returned. Another optional keyword parameter, cutoff (default is 0. 6), allows you to set a threshold for string matching scores.
