When unit-testing a function that make multiple external calls/requests, we want to mock the actual call and return the mock results. For each call, we might want to return different results.

Previously, our projects are still using the old Python 3.10, which will be deprecated soon this year. We are also using the good old pip and venv for the project/package management. This is already posing some issues for us:

• venv is a pure virtual env tool without the ability to manage python versions (it just picks your local python), so it is hard to enforce the local env of each developer
• pip’s requirements.txt is not a lockfile and thus does not ensure a fully reproducible python environment
• pip as a package management tool is not performant enough in resolving and installing packages

In order to solve these problems, I took the effort to migrate our project management to uv. Here are some of the things that I learned in the process as a first-time uv user.

When I am working on a Python project, I am using black to format the code, so that we have a unified format across the code base.

One pain point, however, is the super annoying trailing white spaces:

1. black can remove trailing spaces for doc string, code and comment, but it will not touch trailing spaces in, e.g., multi-line strings.
