[BUG] print does not work well with DefaultDict

[ZhiyuanChen]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

rich.print inspects __rich__ and aihwerij235234ljsdnp34ksodfipwoe234234jlskjdf of object during printing.

However, it does not inspect if the __getattr__ of object will always returns something.

ipython avoids this behaviour by checking _ipython_canary_method_should_not_exist_ before inspecting the object.

from chanfig import Config
from rich import print as pprint


if __name__ == '__main__':
    config = Config(**{'hello': 'world'})
    print('print', config)
    pprint('rich.print', config)
    print(config.__rich__)
    print(config.keys())

rint Config(<class 'chanfig.config.Config'>,
  ('hello'): 'world'
)
rich.print Config(<class 'chanfig.config.Config'>,
  ('hello'): 'world'
  ('__rich__'): Config(<class 'chanfig.config.Config'>, )
  ('aihwerij235234ljsdnp34ksodfipwoe234234jlskjdf'): Config(<class 'chanfig.config.Config'>, )
)
Config(<class 'chanfig.config.Config'>, )
dict_keys(['hello', '__rich__', 'aihwerij235234ljsdnp34ksodfipwoe234234jlskjdf'])

I can't reproduce this with recent Rich:

print Config(<class 'chanfig.config.Config'>,
  ('hello'): 'world'
)
rich.print Config(<class 'chanfig.config.Config'>,
  ('hello'): 'world'
)
<bound method FlatDict.__rich__ of Config(<class 'chanfig.config.Config'>,
  ('hello'): 'world'
)>
dict_keys(['hello'])

I hope we solved your problem.

Yes, since this issue wasn't responded in a long period, I did some hack in chanfig as a temporary solution. See more at ZhiyuanChen/CHANfiG@3155769.

However, this is still an issue. rich will have same behaviour when working with python's collection.defaultdict.

I'm going to need a minimal reproducible example, because Rich does work with default dict as you can see here:

>>> from collections import defaultdict
>>> d=defaultdict(str)
>>> d["foo"] = "bar"
>>> from rich import print
>>> print(d)
defaultdict(<class 'str'>, {'foo': 'bar'})

Thank you. Could you please try use chanfig <= 0.0.81?
