Explore Python dependencies with `pipdeptree` and `uv pip tree`

"Sometimes you just want to know about your dependencies, and their dependencies. I've been using pipdeptree for a while, but recently switched to uv pip tree. Let's take a look at both tools. pipdeptree pipdeptree is pip installable, but I don't want pipdeptree itself to be reported alongside everything else installed, so I usually install it outside of a project. We can use it system wide by: Installing with uv tool install pipdeptree. Then running with pipdeptree --python auto Running without installing with uvx pipdeptree --python auto usage The --python auto tells pipdeptree to look at the current environment. Let's take a look at the dependencies in my cards project:"

"(cards) $ pipdeptree --python auto (resolved python: /Users/brianokken/projects/cards/.venv/bin/python) cards==2.0.0 tinydb [required: ==4.8.2, installed: 4.8.2] typer [required: ==0.17.4, installed: 0.17.4] click [required: >=8.0.0, installed: 8.3.0] typing_extensions [required: >=3.7.4.3, installed: 4.15.0] shellingham [required: >=1.3.0, installed: 1.5.4] rich [required: >=10.11.0, installed: 14.1.0] markdown-it-py [required: >=2.2.0, installed: 4.0.0] mdurl [required: ~=0.1, installed: 0.1.2] Pygments [required: >=2.13.0,<3.0.0, installed: 2.19.2] rich [required: ==14.1.0, installed: 14.1.0] markdown-it-py [required: >=2.2.0, installed: 4.0.0] mdurl [required: ~=0.1, installed: 0.1.2] Pygments [required: >=2.13.0,<3.0.0, installed: 2.19.2]"

pipdeptree can be installed outside a project to avoid listing itself among project dependencies and can be run with --python auto to inspect the current environment. pipdeptree prints a hierarchical tree showing packages, version requirements, and installed versions. A virtual environment with the project installed (editable install) is required to reflect project dependencies accurately. uv provides uv pip tree which shows a similar dependency tree formatted with package names and versions and integrates with uv venv and uv pip commands for managing environments and installs.
