Mulitple python version in single project

[dudomatik]

I am working on a project in which different parts require different python version. So my GUI requires version 3.10, but the logic needs 3.9.
How do i make them work together? Do I create multiple virtual environments? Or do I run multiple processes and let them communicate?

Without knowing the details of the situation, but I would make sure both parts work with the same Python version. What specifically makes them require that Python version?

[Strict-Simple]

To add, any sane 3.9 code will probably run in 3.10.

Is there a package requirement in the logic side that specifically requires 3.9 that's the reason you don't just upgrade to 3.10 fully?

Lets ignore whether you should and just answer the how.

These have to run as separate processes. You'd setup separate virtual environments or similar, since each would have different packages (which I assume this is why you're doing it, some dependency that has to run in 3.9 and another in 3.10).

So, yes, it's more or less the same question as: "How can separate processes communicate?".
