[New-bugs-announce] [issue9733] Can't iterate over multiprocessing.managers.DictProxy

[Juan José Conti]

New submission from Juan José Conti <jjconti at gmail.com>:

I expected I could iterate over a DictProxy as I do over a regular dict.

>>> from multiprocessing import Manager
>>> m = Manager()
>>> d = m.dict()
>>> d
<DictProxy object, typeid 'dict' at 0x98a240c>
>>> for x in d:
...     print x
...
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 2, in __getitem__
  File "/usr/lib/python2.6/multiprocessing/managers.py", line 740, in _callmethod
    raise convert_to_error(kind, result)
KeyError: 0
>>> d['a'] = 1
>>> for x in d:
...     print x
...
