Mapping proxy is quite often used in building . For example types __dict__ are mapping proxy.
>>> bool.__dict__
mappingproxy({'__or__': <slot wrapper '__or__' of 'bool' objects>, '__doc__': 'bool(x) -> bool\n\nReturns True when the argument x is true, False otherwise.\nThe builtins True and False are the only two instances of the class bool.\nThe class bool is a subclass of the class int, and cannot be subclassed.', '__xor__': <slot wrapper '__xor__' of 'bool' objects>, '__and__': <slot wrapper '__and__' of 'bool' objects>, '__rxor__': <slot wrapper '__rxor__' of 'bool' objects>, '__repr__': <slot wrapper '__repr__' of 'bool' objects>, '__new__': <built-in method __new__ of type object at 0x82a1140>, '__rand__': <slot wrapper '__rand__' of 'bool' objects>, '__str__': <slot wrapper '__str__' of 'bool' objects>, '__ror__': <slot wrapper '__ror__' of 'bool' objects>})
Mapping proxy is not a subclass of dict, so pprint doesn't print it pretty. Proposed patch adds support for mapping proxies in pprint.
>>> from pprint import pprint as pp
>>> pp(bool.__dict__)
mappingproxy({'__and__': <slot wrapper '__and__' of 'bool' objects>,
'__doc__': 'bool(x) -> bool\n'
'\n'
'Returns True when the argument x is true, False '
'otherwise.\n'
'The builtins True and False are the only two '
'instances of the class bool.\n'
'The class bool is a subclass of the class int, and '
'cannot be subclassed.',
'__new__': <built-in method __new__ of type object at 0x82a1140>,
'__or__': <slot wrapper '__or__' of 'bool' objects>,
'__rand__': <slot wrapper '__rand__' of 'bool' objects>,
'__repr__': <slot wrapper '__repr__' of 'bool' objects>,
'__ror__': <slot wrapper '__ror__' of 'bool' objects>,
'__rxor__': <slot wrapper '__rxor__' of 'bool' objects>,
'__str__': <slot wrapper '__str__' of 'bool' objects>,
'__xor__': <slot wrapper '__xor__' of 'bool' objects>})
