I have created a ShowInstalledPackages.py program on GitHub (and below).
Works on-line and offline, showing all python packages installed by user, and
detailed information about each.
![[Image: InstalledPackages.png?raw=true]](https://github.com/Larz60p/ShowInstalledPackages/blob/master/InstalledPackages.png?raw=true)
https://github.com/Larz60p/ShowInstalled...ackages.py
Checks if Internet present, if so gets a fresh copy of package info from pip, otherwise loads the last version obtained from a file. Must be run from the internet first time.
Single click on package name will show summary description on bottom frame of GUI.
Double click shows detailed information on the package.
** Note ** The installed version and most recent version are shown at the top of the Detail information. If there is a difference, you should get the updated version.
