So pyproject.toml will be used by uv and others, like poetry. Pip uses a requirements.txt for depandancy management.
Using uv as an example[0]:
uv add "tqdm >=4.66.2,<5"

I don't have access to uv to test that command at the moment, but that should work. uv then installs the dependency in the .venv directory in the project directory. This may include a specific version of python as well, if you pin one.
