[issue13829] exception error in _scproxy.so when called after fork
triccare triccare <tricc...@gmail.com> added the comment: I have run into this bug which can be reliably reproduced by importing tkinter. However, I have found another workaround if one does not want to deal with the environmental variable and may point to a possible bug fix. Before forking, any use of `urlopen` alleviates the bug. This is demonstrated in the attached example. Example works under Python 3.6.4 and Mac OS 10.12.6 -- nosy: +triccare triccare Added file: https://bugs.python.org/file47503/debug_urlopen.py ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue13829> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
Re: Why keys method does not work with MutableMapping?
Ahhh, and what is being shown is simply the __repr__. Gotcha. Thanks!

Why keys method does not work with MutableMapping?
Greetings,
Apologies if this has shown up twice; I jumped the gun sending before
confirming registration.
I have a class that completely implements MutableMapping, meaning that all
the abstract methods are implemented. However, the keys method no longer
returns the keys, but simply a repr of the instance. Example is below.
Same is true for the items method.
It would seem that, if all the abstract methods have been implemented, the
keys and items methods should be able to perform exactly like the native
dict versions. There does not seem to be a need to override these methods.
Thank you for your time.

Code:
from collections import MutableMapping
class MyDict(MutableMapping):
def __init__(self, *args, **kwargs):
self.data = dict(*args, **kwargs)
def __getitem__(self, key):
return self.data[self.__keytransform__(key)]
def __setitem__(self, key, value):
self.data[self.__keytransform__(key)] = value
def __delitem__(self, key):
del self.data[self.__keytransform__(key)]
def __iter__(self):
return iter(self.data)
def __len__(self):
return len(self.data)
def __keytransform__(self, key):
return key
md = MyDict({'a': 1, 'b':2})
md.keys()
