Antoine Pitrou <pit...@free.fr> added the comment:
Actually, making PyMapping_Check() more robust produces a test failure in
test_builtin, because of the following code:
# Verify locals stores (used by list comps)
eval('[locals() for i in (2,3)]', g, d)
eval('[locals() for i in (2,3)]', g, collections.UserDict())
class SpreadSheet:
"Sample application showing nested, calculated lookups."
_cells = {}
def __setitem__(self, key, formula):
self._cells[key] = formula
def __getitem__(self, key):
return eval(self._cells[key], globals(), self)
ss = SpreadSheet()
ss['a1'] = '5'
ss['a2'] = 'a1*6'
ss['a3'] = 'a2*7'
self.assertEqual(ss['a3'], 210)
Should I fix the example to include a keys() method?
