New issue 2223: itertools.islice incompatibility with CPython https://bitbucket.org/pypy/pypy/issues/2223/itertoolsislice-incompatibility-with
Jonas Pfannschmidt: itertools.islice accepts floats as parameters in CPython but not in pypy. CPython (Python 2.7): ``` #!python >>> import itertools >>> itertools.islice([1,2,3,4,5,6,7,8,9], 1.0, 6.0, 2.0) <itertools.islice object at 0x7f14cd0d1e10> ``` pypy: ``` #!python >>>> import itertools >>>> itertools.islice([1,2,3,4,5,6,7,8,9], 1.0, 6.0, 2.0) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: Indicies for islice() must be None or non-negative integers ``` Please note that the behaviour in CPython for Python 3 is again different: ``` #!python >>> import itertools >>> itertools.islice([1,2,3,4,5,6,7,8,9], 1.0, 6.0, 2.0) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: Stop argument for islice() must be None or an integer: 0 <= x <= sys.maxsize. ``` _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
