This is not a bug (and if it were you would have to report to numpy, not cpython). Consider: >>> import numpy >>> a = numpy.zeros((2,2,2)) >>> a[0,2] Traceback (most recent call last): File "<stdin>", line 1, in <module> IndexError: index 2 is out of bounds for axis 1 with size 2 This is probably the message you expect. However, if you write >>> a[0][2] Traceback (most recent call last): File "<stdin>", line 1, in <module> IndexError: index 2 is out of bounds for axis 0 with size 2 you split the operation into two steps, and the second axis of a is effectively the first axis of a[0]. ---------- nosy: +peter.otten -steven.daprano _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39864> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
