interpreters-pep-734 0.5.0

Use this module to try out multiple interpreters and a per-interpreter GIL in Python 3.12+. Do not use this for anything important yet.

This is the public pure-Python implementation of PEP 734, along with several other backports.

For the implementation of the low-level modules, only on Python 3.12, see https://pypi.org/project/interpreters-3-12/.

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
