Python 2 or 3?

[Crunchy Dragon]

Hello programmers!

 

I'm starting to get back into coding, after spending quite some time away. Around 10 years ago, I started learning a little bit of I would have to guess mid-Python 2, which has since vacated my memory. Recently, I used my 7-day free trial of CodeAcademy Pro to learn a bit of Python 3.

 

My trial has since run out, and Python 3 is now hidden behind a lovely paywall. However, Python 2 on CodeAcademy is free to learn.

 

My question is simply this, should I learn Python 2 or 3?

I've read a little bit about it here, but I'm still not 100% sure.

Id learn 3 if you can, 2 is gonna lose support soon, and people are moving away from it.

The difference between python 2 and 3 are pretty small, so if you wanted to use code academy you could follow the python 2 course then just learn the few things that have changed (print became print(), 3 / 2 went from 1 to 1.5, and a few other minor changes).

I would recommend python 3, because python 2 will be end of life fairly soon.

As far as I can tell, there are very few things that work in 2 that don't work in 3. However, there are many features of 3 that are simply not available in 2, like F-strings and more advanced list comprehensions.

The biggest differences that a "beginner" (not that you are one in the strictest sense) would notice is that division of integers now returns some type with a decimal instead of being truncated division, and the "print" statement has been updated to have the same syntax as all other builtin functions, "print()". Another feature that a beginner with experience in python 2 would notice is that there are now more string formatting options than the old C-like syntax.

In regards to the first change, truncated division is now done by using the "//" operator.

 

Unless you specifically want to use some outdated libraries that only work with 2.7, I would strongly recommend learning 3.7.

Write in C.

they are very similar in syntax, but learn 3

Learn 3 - 2 is going away beginning of 2020
