It is possible to use And (0 < x, x < 1) instead, but in your example this is unnecessary. Recall that the conditions are evaluated from left to right; the first that evaluates to True wins. d6warn noticeWeb1 You should modify x >= lower and x <= upper to (x >= lower) & (x <= upper) . The problem is that logical evaluations with SymPy objects can return an another symbolic logic that cannot be deduced to True or False. You can see how (x >= lower).__class__ returns an another sympy inequality instance. Share Improve this answer Follow d6wn36ad anydes2WebApr 23, 2024 · billzorn mentioned this issue on Aug 2, 2024.
