You, who is starting with Python, must have, at some point, faced this doubt: Which version of Python should we learn. At first, these questions may seem a bit pointless to programmers who come from other languages, such as Java, that support backward compatibility in each version upgrade, but Python 3, without a doubt, ends with some functionalities and specificities of the previous versions, and that can end up in a lot of trouble.

This talk aims to take make it clear in why everyone should use Python 3 over Python 2, understanding what truly are the differences between each version (and why do they exist) and how can we, as developers, convert our programs to Python 3 and abandon
