in CPython, instead of trying each object and function,
is there any rules can help me answer the following questions ? or is there any third part documentations [community driven docs ? wiki ?] that can answer them ? 1. 'setattr(o, name, value)' can be used for what kind of objects ? section '2. Built-in Functions' of the official documentation says : > The function assigns the value to the attribute, provided the object allows it. 2. what kind of functions does not have signature, so that 'inspect.signature(f)' can be used for them ? section '29.12.3. Introspecting callables with the Signature object' of the official documentation says : > Some callables may not be introspectable in certain implementations of Python. > For example, in CPython, some built-in functions defined in C > provide no metadata about their arguments. this is depends on implementation, so I ask for CPython. ------ xyh -- https://mail.python.org/mailman/listinfo/python-list
