interpreters-pep-734 0.4.1

Use this module to try out multiple interpreters and a per-interpreter GIL in Python 3.13+. Do not use this for anything important yet.

This is the public implementation of PEP 734.

Nearly all development for this project is done in the upstream CPython repo.

---

This PyPI package installs two modules: interpreters_backports and interpreters_experimental. The "backports" module is a package that mirrors the backported structure of the 3.14 modules. The "experimental" module is a package containing modules that may end up in the stdlib.

Note that only the interpreters and interpreters.queues modules are part of PEP 734.

You can use the modules as fallbacks:

try:
    import interpreters
except ModuleNotFoundError:
    from interpreters_backports import interpreters

try:
    import interpreters.queues
except ModuleNotFoundError:
    import interpreters_backports.interpreters.queues
    from interpreters_backports import interpreters

try:
    from interpreters import channels
except ModuleNotFoundError:
    from interpreters_experimental.interpreters import channels

try:
    from concurrent.futures import ThreadPoolExecutor
except ModuleNotFoundError:
    from interpreters_backports.concurrent.futures import ThreadPoolExecutor
