Re: python 3.2 support

We do create a python3 package for MonetDB for Ubuntu 12.04. If you follow the instructions on http://dev.monetdb.org/downloads/deb/ to enable the apt repository, you can apt-get install python3-monetdb. On 2014-03-13 00:14, Simon wrote:

Within the MonetDB sources (clients/python3) you can find a python3 module. I think Gijs only put the python2.x code on pypi.
