Maybe not "numpy arrays duck-type as collections", but it is very common that arrays and sequences are used interchangably. Numpy has created the term "array-like" for this. Well technically, an array-like is something that `np.array()` can turn into an array. But from a user point of view array-like effectively means array or sequence. If you want to write a function that accepts array-like `values`, you have to change a check `if values` to `if len(values) == 0`. That works for both but is against the PEP8 recommendation. This is a shortcoming of the language. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/ETQ4UJTVQLW2WNQWZTWKBWGSY2JRHRA4/ Code of Conduct: http://python.org/psf/codeofconduct/
