Example use: async with asyncio.TaskGroup() as group: task1 = group.create_task(some_coroutine(...)) task2 = group.create_task(other_coroutine(...)) print("Both tasks have completed now.") All tasks are awaited when the context manager exits. Any exceptions other than `asyncio.CancelledError` raised within a task will cancel all remaining tasks and wait for them to exit. The exceptions are then combined and raised as an `ExceptionGroup`. c � � d| _ d| _ d| _ d | _ d | _ d| _ t � � | _ g | _ d | _ d | _ d S )NF) �_entered�_exiting� _aborting�_loop� _parent_task�_parent_cancel_requested�set�_tasks�_errors� _base_error�_on_completed_fut��selfs �?/opt/alt/python-internal/lib64/python3.11/asyncio/taskgroups.py�__init__zTaskGroup.__init__ sV � � �� � �� � ����� � ���(-��%��e�e�� ��� � ���!%�� � � � c �t � dg}| j r*|� dt | j � � � �� � | j r*|� dt | j � � � �� � | j r|� d� � n | j r|� d� � d� |� � }d|� d�S ) N� ztasks=zerrors=� cancelling�entered� z <TaskGroup�>)r �append�lenr r r �join)r �info�info_strs r �__repr__zTaskGroup.__repr__( s� � ��t�� �;� 5� �K�K�3��T�[�!1�!1�3�3� 4� 4� 4� �<� 7� �K�K�5�#�d�l�"3�"3�5�5� 6� 6� 6� �>� #� �K�K� � %� %� %� %� �]� #� �K�K� � "� "� "��8�8�D�>�>��'�H�'�'�'�'r c � � K � | j rt d| �d�� � �| j �t j � � | _ t j | j � � | _ | j �t d| �d�� � �d| _ | S )N� TaskGroup z has already been enteredz! cannot determine the parent taskT)r � RuntimeErrorr r �get_running_loopr � current_taskr r s r � __aenter__zTaskGroup.__aenter__6 s� � � � � �=� @� �>�T�>�>�>�@� @� @� �:� � �0�2�2�D�J� !� .�t�z� :� :��� � � $� �F�T�F�F�F�H� H� H� �� �� r c � � K � d| _ |�#| � |� � r| j �|| _ |t j u r|nd }| j r | j � � � dk rd }|�| j s| � � � | j r{| j � | j � � � | _ | j � d {V �� n9# t j $ r'}| j s|}| � � � Y d }~nd }~ww xY wd | _ | j �{| j rJ �| j �| j �|r | j s|�|�(|t j ur| j � |� � | j r% t! d| j � � }|d �# d | _ w xY wd S )NT� z unhandled errors in a TaskGroup)r �_is_base_errorr r �CancelledErrorr r �uncancelr �_abortr r r � create_futurer r �BaseExceptionGroup)r �et�exc�tb� propagate_cancellation_error�ex�mes r � __aexit__zTaskGroup.__aexit__D s� � � � � �� � �O��#�#�C�(�(� �� �(� "�D� � ��2�2�2�C�C�� %� � (� 4�� �)�)�+�+�q�0�0� 04�,� �>��>� � � � � � � � �k� *��%�-�)-��)A�)A�)C�)C��&� "��,�,�,�,�,�,�,�,�,�� �,� "� "� "��~� "� 46�0��K�K�M�M�M���������� "���� &*�D� "�' �k� *�* �;� � �� � � '��"� "� (� /�� � /�.� .� �>�b� �(A� A� A� �L� � �� $� $� $� �<� $� $�'�(I�4�<�X�X���d�"�� #�� �#�#�#�#� $� $s$ �1 B? �?C5� C0�0C5�E2 �2 E;N)�name�contextc � � | j st d| �d�� � �| j r| j st d| �d�� � �| j rt d| �d�� � �|�| j � |� � }n | j � ||�� � }t j ||� � |� | j � � | j � |� � |S )zbCreate a new task in this group and return it.
