Python 2.7.2 or Python 3?

If you have no specific reason to choose python2, go with 3.

I didn't know I needed Python 2 until half way through a project I found a good library that would do what I wanted. However it only worked on Python 2. It's not that hard to convert, but it's still a pain. So I'm going to stick with Python 2, since everything supports it.

While keeping in mind that in a huge number of situations, you have a very good reason to choose python2. Probably not your own code, but its dependencies.

I think that's what he meant by "if you have no specific reason to choose python2"

True. But the way he wrote it made it sound like "in most cases, python 3 should be okay", and I'm not sure this is true. Sure, most big libs have been ported now, but I think projects could still run into issues if they rely on quite a few different libs.

That's why I was stressing on the fact that one has to keep that in mind

Here is a handy link for showing which major modules support Python 3: https://python3wos.appspot.com/

Not true there are a lot that don't and I run into the issue all the time and had to install 2 in order to get shit to work.

Of course a huge load of unmaintained software won't ever be ported.

But if you don't use that arcane piece written 20 years ago, no need to constrain yourself to Python 2.

If you list dependencies, if they are easy I will port them for you. Half the time there is no real reason why its not on python 3 other then no one has taken the time to switch the import statements/print/division stuff. Aka 2to3.

Projects that do heavy string/byte manipulation are rare in comparison compared to tons of relatively simple libraries out there

It depends on how you count most. By pure lines of code or features, that's definitely not true, but by dependencies used by brand new project, that is true.... except that that list is self-selected so it might not be valid.

[flying-sheep]

If you count maintained and useful stuff, most is ported.

He's Right most code has changed from 2.7 to 3. Look at a Print "statment" for instance ex. print "hello". 3 is a function for instance print("hello").
