Convert python 2 scripts to python 3

Below is a non-exhaustive list of common things to do to convert your scripts to python 3.

Mandatory:

• print ... becomes print(...),

• myDict.iterkeys(), myDict.itervalues(), myDict.iteritems() becomes myDict.keys(), myDict.values(), myDict.items(),

• import cPickle becomes import pickle,

• `` and <> operators are no longer recognized,

• inconsistent use of tabs and spaces in indentation is prohibited, for this reason all scripts in yade use tabs for indentation.

Should be checked, but not always mandatory:

• (euclidian) division of two integers: i1/i2 becomes i1//i2,

• myDict.keys(), myDict.values(), myDict.items() becomes sometimes list(myDict.keys()), list(myDict.values()), list(myDict.items()) (depending on your usage),

• map(), filter(), zip() becomes sometimes list(map()), list(filter()), list(zip()) (depending on your usage),

• string encoding is now UTF8 everywhere, it may cause problems on user inputs/outputs (keyboard, file…) with special chars.

Optional:

• # encoding: utf-8 no longer needed
