Python versions

Question

In SoloLearn, only version 3 of the Python language is available. But currently Python works in version 3.9! What if I learn this language from version 3? Is it harmful?

Answer 1

You can try this :

import sys
print(sys.version)
print(sys.version_info)

Sololearn is on Python 3.8.6 currently, "Python 3" refers to the major version (the first number of the three)
Python 2 is no longer officially supported. But it comes preinstalled in many Linux distributions. There are some syntax differences between version 2 and 3.

Every minor version (the second number) brings about a few new features. They tend to be published in every few months, maybe a year. And occasionally, Sololearn also upgrades to a newer version. So you are not losing out on anything, except the very latest features. Once you are already familiar with the currently available version, it is not a big deal to keep track of new things, just read some blog posts and you can install any version on a computer to try.

Answer 2
