Python version Detector

Sometimes you find the right exploit, but you turn your back and don’t use it cause it spawns only errors.

I noticed this when a script is written in the Python language.

Keep in mind that exploits can be new (written in python3) or older (written in python/python2)

I created this to identify the version you should use easily.

Also, pay attention to how it got detected, that way you will learn by using it yourself how to identify with simple logic the versions in the future without using the script!
