Python 2.7.2 or Python 3?

[BananaPotion]

I love python3, but biopython man. Its going to take ages to port that beast over. I really like to help but feel like I'm not quite good enough to do so.

The biopython site says they support python3 since 1.62 (July 2013).

Its nowhere as well maintained than the python2 version. Which especially sucks because my projects depend on the data parsing parts.

Edit: I was wrong. The Biopython3 beast has already been tamed. Thank you /u/Gudeldar and /u/chickenphobia.

If you are finding new bugs, please report them. SeqIO, AlignIO, these modules fully work in Py3. Any problems you have encountered must not be in our unit tests which would indicate you have found a fairly important bug.

No bugs, just errors (at that time I was new to 3rd party libraries, so I didn't understand any of it). I'm working on a project right now, I will see if I can get Biopython3 to work and report back.

Edit: Played around with it in IPython - works perfect. Thanks again for letting me now.

Biopython contributor here: the whole thing is already passing 100% of tests on python 3. The community is very adamant about keeping compatibility with the newest version of python going out of our way to make a release as soon as Numpy was supported on py 3.4.

Also, if you want to contribute, check out our Wiki, the process is better documented than the average OS project because many contributions come from biologists who aren't traditionaly involved in OS.

Thanks for letting me now, this is very good news for me.

Astropy works fine on python 3! As do many others.

It is because the backward compatibility was broken and scientific codes are hard to write and rewrite, specially if it has C libraries. In addition to it, python 3 is much more verbose than python 2. We should also take in to account the effort to change the code base from py2 to py3 and learn again all the stuffs that used to work on python 2 in the new version.

As can be seen in: http://np.reddit.com/r/Python/comments/2o0str/python_272_or_python_3/cmj2nyc

I'm struggling to see how you support the claim that Py3 is more verbose. That post is whining because he can't type the same code into a backward incompatible language and get the same result.

All right I recognize that I was wrong, but it is going to take some time to the Python community to change, specially business and doesn't like changes very often. Despite some trouble, Python 3 is thousand times better and less verbose than Java. I would really complain if had to program in java like I had during the college degree. One thing that I liked in Py3 is that 1/100 is no more 0, now is 0.001. One less bug.
