Re: List slicing on Python 2.7

Found the answer on stack overflow. Some types on some runtimes (builtins and on Python 2) use another method __getslice__ instead of __getitem__. https://docs.python.org/2/reference/datamodel.html#object.__getslice__ czw., 15 mar 2018 o 12:54 użytkownik Arkadiusz Bulski

List slicing on Python 2.7

I have a custom class (a lazy list-like container) that needs to support slicing. The __getitem__ checks if index is of slice type, and does a list comprehension over individual integer indexes. The code works fine on Python 3 but fails on 2.7, both CPython and PyPy. The print inside __getitem__
