Pending removal in Python 3.21

• abc

  • Soft-deprecated since Python 3.3 abc.abstractclassmethod, abc.abstractstaticmethod, and abc.abstractproperty now raise a DeprecationWarning. These classes will be removed in Python 3.21, instead use abc.abstractmethod() with classmethod(), staticmethod(), and property respectively.

• ast:

  • Classes slice, Index, ExtSlice, Suite, Param, AugLoad and AugStore, will be removed in Python 3.21. These types are not generated by the parser or accepted by the code generator.

  • The dims property of ast.Tuple will be removed in Python 3.21. Use the ast.Tuple.elts property instead.

• struct:

  • Soft-deprecated since Python 3.15, using 'F' and 'D' type codes are now deprecated. These codes will be removed in Python 3.21. Use instead two-letter forms 'Zf' and 'Zd'.

• tempfile:

  • tempfile._TemporaryFileWrapper will be removed in Python 3.21. Use the public tempfile.TemporaryFileWrapper instead.

• threading:

  • threading.Condition.notifyAll, threading.Event.isSet, and threading.activeCount will be removed in Python 3.21. Use the snake case names (e.g., notify_all) instead.

  • threading.Thread.isDaemon, threading.Thread.setDaemon will be removed in Python 3.21. Use the property threading.Thread.daemon instead.

  • threading.Thread.getName and threading.Thread.setName will be removed in Python 3.21. Use the property threading.Thread.name instead.
