When they suggest you pin your dependencies, they don't just mean your direct dependencies, but rather all transitive dependencies. You can take this further by having a lock file that account for different Python versions, operating systems, and CPI architectures – for instance , by using UV or Poetry – but a simple `pip freeze` is often sufficient.

- dagw 2y agoThat works for your project, but then nobody can include you as a library without conflicts. I think this is the core to much misunderstandings and arguments around this question. Some people are writing code that only they will run, on a python they've installed, on hardware they control. Others are writing code that has to work on lots of different versions of python, on lots of different hardware, and when being run in all kinds of strange scenarios. These two groups have quite different needs and don't always understand each other and the problems they face.
- zelphirkalt 2y agoA lib can still lock its dependencies and have version ranges declared at the same time. The lock file is an artifact than is used to reproducibly build the lib, while the version ranges are used to see, whether some other project can use the lib. It is only a matter of tooling. Locking ones dependencies remains the right thing to do, even for a lib.
