New issue 1819 by [email protected]: _sympify(True) == 1 http://code.google.com/p/sympy/issues/detail?id=1819 In [1]: from sympy.core.sympify import _sympify In [2]: _sympify(True) Out[2]: 1 In [3]: _sympify(False) Out[3]: 0 This is surprising and undocumented. It also leads to results like S(1) + True == 2, which is mathematically inconsistent, though consistent with Python's inconsistencies. Existing code relies on _sympify to only output sympy objects, so it should probably raise a SympifyError on booleans. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
