I fell like it's a bit weird to have a new function just for ignoring case, will a new function be required for every possible normalization like removing accents. One possible make the API handle those use cases would be to have a keyword-argument for this:


>>> difflib.get_close_matches('apple', ['APPLE'], normalization=str.lower)
['APPLE']

Then it could work with other normalization too without requiring a new function every time:

>>> difflib.get_close_matches('Remi', ['Rémi'], normalization=remove_a ccents)
['Rémi']
