multiprocessing provides a way to perform multi-process based parallelism. It’s built into Python. Pint provides a unit library to conduct automatic conversion between physical unit systems. PyTables provides a reader and writer for HDF5 format files. PyMC3 provides Bayesian statistical modeling and...
multiprocessing also now has the concept of a context, which determines how child processes are created. New function get_context() returns a context that uses a specified start method. It has the same API as the multiprocessing module itself, so you can use it to create Pools and other obj...

multiprocessing.Process now accepts a daemon keyword argument to override the default behavior of inheriting the daemon flag from the parent process (bpo-6064). New attribute multiprocessing.Process.sentinel allows a program to wait on multiple Process objects at one time using the appropriate OS pri...

Skip tests if the multiprocessing.synchronize module is missing, if there is no available semaphore implementation, or if creating a lock raises an OSError. 3.10 新版功能. test.support.check_disallow_instantiation(test_case, tp, *args, **kwds) Assert that type tp cannot be instantiated using ...
Some significant new packages have been added to the standard library, such as themultiprocessingandjsonmodules, but there aren't many new features that aren't related to Python 3.0 in some way. Python 2.6 also sees a number of improvements and bugfixes throughout the source. A search through...
