I faced with broken add-apt-repository on my KDE Neon after upgrading to Ubuntu 22.04

When I started working at Red Hat my first job was contribution to integration tests of one web application. The tests are written Python and the repository has both setup.py and requirements.txt. But why?

Debugging is an essential part of programming. I guess you can agree with me that it takes significant amount of time. Using an appropriate tool can save your time and efforts.

In programming it's quite often you need to wait for an action to complete or some service availability. There are many ways and tools which able to do that. I would like to tell about two python libraries I've worked with.
