Issue 1178: sympify uses a mutable object with a keyword argument http://code.google.com/p/sympy/issues/detail?id=1178
New issue report by ellisonbg: The current implementation of sympify looks like: def sympify(a, locals= {}): ... This causes locals to be remembered between calls to sympify: The easiest way of seeing this is to do the following in isympy: In [1]: sympify('x') Out[1]: x In [2]: sympify? You will see that locals is no longer an empty dict, but the user's entire locals namespace, from the previous call to sympify. The fix is to do: def sympify(a, locs= None): if locs is None: locals = {} else: locals = locs ...
