Comment #33 on issue 1233 by [email protected]: fix the rest of jython bugs
http://code.google.com/p/sympy/issues/detail?id=1233
I don't know if this is what you meant, but it doesn't fix the problem:
diff --git a/sympy/core/sets.py b/sympy/core/sets.py
index d191571..adda53c 100644
--- a/sympy/core/sets.py
+++ b/sympy/core/sets.py
@@ -257,8 +257,8 @@ def __invert__(self):
def __contains__(self, other):
symb = self.contains(other)
- result = ask(symb)
- if result is None:
+ result = isinstance(sym, bool)
+ if not result:
raise TypeError('contains did not evaluate to a bool: %r' %
symb)
return result
And in case you were wondering if the cache was related because of the
cache line in the traceback, I tried with the cache off and it's still the
same error and traceback (except without the cache call of course).
