New issue 2710 by brad.froehle: Cannot simplify Piecewise
http://code.google.com/p/sympy/issues/detail?id=2710
If one uses an "otherwise" option in Piecewise, sympy is unable to simplify:
from sympy.abc import a
from sympy import Piecewise
f = Piecewise((0, a>0), (1, True))
f.simplify()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/pymodules/python2.7/sympy/core/expr.py", line 1905, in
simplify
return simplify(self)
File "/usr/lib/pymodules/python2.7/sympy/simplify/simplify.py", line
1637, in simplify
expr = powsimp(expr, combine='exp', deep=True)
File "/usr/lib/pymodules/python2.7/sympy/simplify/simplify.py", line
1200, in powsimp
return expr.func(*[powsimp(t, deep, combine, force) for t in expr.args])
File "/usr/lib/pymodules/python2.7/sympy/simplify/simplify.py", line
1200, in powsimp
return expr.func(*[powsimp(t, deep, combine, force) for t in expr.args])
File "/usr/lib/pymodules/python2.7/sympy/simplify/simplify.py", line
1187, in powsimp
if expr.is_Pow:
AttributeError: 'bool' object has no attribute 'is_Pow'
