Comment #1 on issue 2230 by [email protected]: Problem in is_Function ans is_Number
http://code.google.com/p/sympy/issues/detail?id=2230
This is not a bug. x.is_Something (capital letter) is a replacement for isinstance(x, Something). If you want to check if a complex expression is a number the use is_number property, e.g.:
In [1]: sin(1).is_number Out[1]: True In [2]: sin(1).is_Number Out[2]: False -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
