It is normally the case that we put in a software on our technique, and it turns out that it is the completely wrong edition. This can lead to compatibility and overall performance troubles because it may not connect with 3rd-party modules adequately. Related is the situation with Python, and as vigilant programmers, we have to figure out the accurate edition that we have to have. For that reason, in this information, we will demonstrate you how to install a precise variation of Python on your Ubuntu process.

Acquiring performed that, we go on to downloading Python and setting up it. For the sake of exhibiting you how to install a distinct version, we will be downgrading our Python from 3.8.5 to Python 2.7.

Initial, we improve the present-day directory to the Downloads folder in which we want to download the package. This can be completed by running the command down below.
