I read PEP 450 as saying that statistics.py can be used by "any secondary school student". This is not true for most Python libraries. In this context, the difference between a float and an int is important. Consider statistics.median([2] * n) As a secondary school student, knowing the definition of median, I might expect the value to be 2, for any n > 0. What else could it be. However, the present code gives 2 for n odd, and 2.0 for n even. I think that this issue is best approached by taking the point of view of a secondary school student. Or perhaps even a primary school student who knows fractions. (A teacher might use statistics.py to create learning materials.) By the way, 2 and 2.0 are not interchangeable. For example >>> [1] * 2.0 TypeError: can't multiply sequence by non-int of type 'float' ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35698> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
