New issue 3791 by [email protected]: AttributeError: 'Mul' object
attribute 'is_commutative' is read-only, when a try to do sympy.integrate()
http://code.google.com/p/sympy/issues/detail?id=3791
My version is 0.7.2-git:
I think there is a bug in:
sympy\core\operations.py, line 57,
where it is:
obj.is_commutative = is_commutative
should be:
obj.__class__.is_commutative = is_commutative
I searched everywhere in all the other .py files and this was the only spot
I could find this attempt to change obj.is_commutative.
Please, let me know if you need files etc...
