Kijk eens bij "fuzzy matching". Enkele geweldige tools in de thread hieronder die overeenkomsten tussen strings berekent.
Ik ben vooral dol op de difflib-module
>>> get_close_matches('appel', ['ape', 'apple', 'peach', 'puppy'])
['apple', 'ape']
>>> import keyword
>>> get_close_matches('wheel', keyword.kwlist)
['while']
>>> get_close_matches('apple', keyword.kwlist)
[]
>>> get_close_matches('accept', keyword.kwlist)
['except']
