Ask HN: Should I learn Python 3 or Python 2?

#1

Post by webbrahmin »

I plan to explore data science and machine learning. After looking into some MOOCs and other online learning resources I have come to the conclusion that a firm grasp of Python is essential. I am new to Python, so my question is should I learn Python 2 or Python 3?

Edit: Corrected a typo.

Python 3 for sure. Even if some major libraries are not yet supported is just a matter of time for them to be 3 compatible. And on top of that, you get a lot of goodies in python 3 specially around string manipulation and dictionaries. Take a look at this [0] post from the python community about python 3 vs 2.

Learn? 3, but really both - apart from string encoding, there are almost only small syntax differences. Nothing that would make you go "I don't know what it does, I don't know python 2".

Use? 3 if possible, unless some super important library is not updated. 2 is going away at some point. Let it die.

There aren't any differences important enough to worry about at the "I am learning Python" level. Down the road, problems between one and the other will get resolved by Googling into StackOverflow, blogs, and the Python documentation. Googling to resolve problems is part of learning Python...and every other programming language these days. Hence Googling for answers is part of learning to program.

Good luck.
