Comment #5 on issue 1648 by asmeurer: trigsimp fails http://code.google.com/p/sympy/issues/detail?id=1648
There is one exception Python's strange comparison rules. Complex numbers, which cannot be ordered, raise an exception if you try to compare them: >>> 1j > 0 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: no ordering relation is defined for complex numbers Does anyone know of a PEP or Python documentation page that explains Python's strange allowing of comparison of unrelated types, like >>> "s" > [] True or even how it is done. I would have guessed hash values, but lists are unhashable. Whatever it is, it seems to maintain the trichotomy and transitivity, which if we define any kind of comparison, it should hold those two laws. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
