Why python programmers hate python 3?

More compatible libraries. There's no reason to use python3 other than having some oddly specific fetish for the number 3. Everything good in python3 was backported to 2.7.

python is completely dropping support for 2, in a few years there were be no updates of any kind even for security issues.

Why people not know how to use the word "do"?

Are you trying to be inflammatory on purpose faggot?

this is bull shit.
