It has long been possible to run multiple Python interpreters in the same
process — via the C API, but not within the language itself.
Eric Snow has been working to make this ability
available in the language for many years.
Now, Snow has published
PEP 734 (“Multiple Interpreters
in the Stdlib”), the latest work in his
quest, and
submitted
it to the Python steering council for a decision.
If the PEP is approved, users will have
an additional option for writing performant parallel Python code.
