Indeed, https://docs.python.org/2/reference/expressions.html#membership-test-details states: For the list and tuple types, x in y is true if and only if there exists an index i such that x == y[i] is true. Now, to check if IronPython honors this. > assert a in (a,), 'a is in (a,)' > assert a in (b,), 'a is in (b,)' # this one fails... > As far as I can see via breakpoints, the Equals methods of the > objects are never actually called, except on the first assertion with the == > operator. My guess is it's cutting corners by comparing hashes instead. -- Regards, Ivan Pozdeev _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org https://mail.python.org/mailman/listinfo/ironpython-users
