Remove python upper bound

[edmondchuc]

Currently, testcontainers-python has this upper bound specified for the python version.

testcontainers-python/pyproject.toml

Line 83 in 3f66784

python = ">=3.9.2,<4.0"

In most cases, testcontainers is used as a dev dependency, but this upper bound ends up forcing downstream libraries to include the same restriction even when it’s not a true runtime dependency. This feels a bit too restrictive and adds extra maintenance burden for library authors.

Could we consider removing the upper bound? Thanks!

like this? see if depending on this branch instead of the published version on pypi fixes it - https://github.com/testcontainers/testcontainers-python/tree/fix/no-max-python-version

here is the commit: d594a74

what package management do you use at work, btw?

I haven't tested it yet but yes, the change in your commit should work.

I use both uv and poetry.

turns out we had a couple libraries that suffer from this
