Python-程式優化設計-module

class Objects, values and types CPython implementation detail:  For CPython,  The standard type hierarchy User-defined functions __doc__ The function’s documentation string, or  None  if unavailable; not inherited by subclasses Writable __name__ The function’s name Writable __qualname__ The function’s  qualified name New in version 3.3. Writable __module__ The name of the module the function was defined in, or  None  if unavailable. Writable __defaults__ A tuple containing default argument values for those arguments that have defaults, or  None  if no arguments have a default value Writable __code__ The code object representing the compiled function body. Writable __globals__ A reference to the dictionary that holds the function’s global variables — the global namespace of the module in which the function was defined. Read-only __dict__ The namespace supporting arbitrary function attributes. Writable __closure__ None ...
