Is there a way to specify distinct requires-python for development and for releases of a project that is release as a pypi library?

[fgmacedo]

I'm the author of a library called python-statemachine.

The library only optionally depends on pydot, and the lib works on Python3.7+.

But I'm suffering to keep working on the project in development mode if I set requires-python = ">=3.7", It stops resolving dependencies even if they were on dev/test groups, for example, myst-parser requires Python>=3.8.

I develop on Python 3.12, and have a test matrix from 3.7..3.12 on GitHub as CI.

Is it possible to get this?

Best!

PS: I currently use Poetry and considering other alternatives as I cannot figure out how to accomplish this.

if you make sure some dependencies will only be used on Python 3.8+, restrict it with environment markers:

myst-parser; python_version>="3.8"

and it can be resolved correctly.

also, the new feature #2995 to be landed in the next release will also help in this case
