What to do with Python 2

We know that Python 2 is no longer officially supported by language developers. Due to the lack of security patches, it should be considered unsafe. But is it dead yet?

Probably not. Even relatively popular open-source libraries can lose the interest of their authors and contributors over time. It also happens that some better alternatives appear, and there's simply no point in developing the original library anymore. Such libraries are often left unmaintained, so no one could update them for compatibility with Python 3.

One of the important reasons why Python 3 couldn't take off for a long time was the sluggish release processes of many Linux distributions. Distribution maintainers often aren't inclined toward the fast adoption of new language versions, especially if these versions break backward compatibility and require patches of other software. Many Python programmers are Linux users, and if they don't have access to the latest...
