mocpy does not work in python 3.4

[haussel]

Hello,

I am interested in using mocpy, but rather would like to work in python 3.4 rather than in 2.7. I have a MOC file that I am trying to read. In python 2.7 it works fine:
Python 2.7.11 (default, Dec 5 2015, 23:51:51)
Type "copyright", "credits" or "license" for more information.

IPython 4.0.1 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.

In [1]: from mocpy import MOC

In [2]: mc = MOC.from_file('/Users/haussel/Downloads/Herschel-Stripe-82_MOC.fits’)

In python 3.4 I get the following error:

Python 3.4.4 (default, Dec 21 2015, 04:54:59)
Type "copyright", "credits" or "license" for more information.

Hi Hervé,

thank you for the bug report. Could you provide me with the MOC you try to read ? That would help.
Thanks!

Should be fixed now.
Running pip install --upgrade mocpy will get you the latest version
