I didn't understand how to use ** \ _ \ _dict \ _ \ _ in Python. ** ** I saw a good example Shown.
At the following site Using ** \ _ \ _ dict \ _ \ _ **, List of objects that can take the len function as an argument How to find out was shown.
>>> builtin_sized_types =  >>> >>> >>> for val in __builtins__.__dict__.values(): ... if isinstance(val, type): ... if hasattr(val, '__len__'): ... builtin_sized_types.append(val) ... >>> print(*builtin_sized_types, sep='\n')
<class 'memoryview'> <class 'bytearray'> <class 'bytes'> <class 'dict'> <class 'frozenset'> <class 'list'> <class 'range'> <class 'set'> <class 'str'> <class 'tuple'> >>>
If you don't get used to it, you can't use it like this. .. .. I feel like I've learned. Please give me any advice.
