Hey Guys, Sorry for the repost. I have already posted this some months ago but it received no answer on sage-support. I am afraid this is a bug but the guidelines ask to first post here before reporting something on trac. Could you look into this (I have done the best to illustrate the problem):
I am new to Sage and Python. I have encountered a problem with importing form __future__. The commands that I execute work perfectly on a pure python environment but apparently there is some kind of problem introduced by the preparser. The problem is that I cannot "from __future__ import print_function" that is I cannot import the more up-to-date functionality of print as a function. The only workaround is turning the SAGE preparser temporarily off. An other secondary bug appears to be the fact that it is impossible to evaluate preparser(False) and from __future__ import command in the same cell while doing it in two separate cells works perfectly. This was a filed bug in some previous SAGE version (cannot find the relevant ticket in the trac) but although marked as closed apparently is still present. A notebook that fully explains the problem is published at: http://www.sagenb.org/home/pub/2155 Can you look into this and tell me if I should file a bug report. Or maybe somebody more expert can do this. Best Regards, Gennady N.
