17. Concurrent Execution
The modules described in this chapter provide support for concurrent execution of code. The appropriate choice of tool will depend on the task to be executed (CPU bound vs IO bound) and preferred style of development (event driven cooperative multitasking vs preemptive multitasking). Here’s an overview:

threading— Thread-based parallelism - 17.2.
multiprocessing— Process-based parallelism- 17.2.1. Introduction
- 17.2.2. Reference

Processand exceptions - 17.2.2.2. Pipes and Queues
- 17.2.2.3. Miscellaneous
- 17.2.2.4. Connection Objects
- 17.2.2.5. Synchronization primitives
- 17.2.2.6. Shared
ctypesObjects - 17.2.2.7. Managers
- 17.2.2.8. Proxy Objects
- 17.2.2.9. Process Pools
- 17.2.2.10. Listeners and Clients
- 17.2.2.11. Authentication keys
- 17.2.2.12. Logging
- 17.2.2.13. The
multiprocessing.dummymodule
- 17.2.2.1.
- 17.2.3. Programming guidelines
- 17.2.4. Examples
