shutil.rmtree() is a function in Python that recursively deletes the entire directory tree. It can delete specified folders and all contents. 1. Basic usage: Use shutil.rmtree(path) to delete the directory, and you need to handle FileNotFoundError, PermissionError and other exceptions. 2. Practical application: You can clear folders containing subdirectories and files in one click, such as temporary data or cached directories. 3. Notes: The deletion operation is not restored; FileNotFoundError is thrown when the path does not exist; it may fail due to permissions or file occupation. 4. Optional parameters: Errors can be ignored by ignore_errors=True

Use multiprocessing.Queue to safely pass data between multiple processes, suitable for scenarios of multiple producers and consumers; 2. Use multiprocessing.Pipe to achieve bidirectional high-speed communication between two processes, but only for two-point connections; 3. Use Value and Array to store simple data types in shared memory, and need to be used with Lock to avoid competition conditions; 4. Use Manager to share complex data structures such as lists and dictionaries, which are highly flexible but have low performance, and are suitable for scenarios with complex shared states; appropriate methods should be selected based on data size, performance requirements and complexity. Queue and Manager are most suitable for beginners.
