The dependencies of the installed Python packages can be listed using the built-in
pip show command.
Alternatively the dependencies can be shown as a tree structure using the
In this note i will show several examples of how to list dependencies of the installed Python packages.

Show Python Package Dependencies
Use the built-in
pip show command to list dependencies of the Python packages that has already been installed, e.g.:
$ pip show Flask Name: Flask Version: 1.1.2 ... Requires: click, Werkzeug, itsdangerous, Jinja2
Show requirements of the all installed Python packages:
$ pip freeze | cut -d "=" -f1 |\ xargs pip show |\ grep -i "^name\|^version\|^requires"

If you don’t mind installing new packages, you can install the
pipdeptree that displays information about the dependencies as a tree structure:
$ pip install pipdeptree $ pipdeptree skywriter==0.0.7 - RPi.GPIO [required: Any, installed: 0.7.0] touchphat==0.0.1 - cap1xxx [required: Any, installed: 0.1.3] - RPi.GPIO [required: Any, installed: 0.7.0] ...
It also can show the dependency tree in the reverse fashion, i.e. list the sub-dependencies with the list of Python packages that require them:
$ pipdeptree -r -p RPi.GPIO RPi.GPIO==0.7.0 - automationhat==0.2.0 [requires: RPi.GPIO] - blinkt==0.1.2 [requires: RPi.GPIO] - Cap1xxx==0.1.3 [requires: RPi.GPIO] - drumhat==0.1.0 [requires: cap1xxx] ...
