Starting from version 9.0, the default distributed version of Sage is using Python 3. See Python3-Switch for more information. |
Main caveat
range and xrange
In Python range is a function that return a list.
In Python 3, range is an object that somehow behave as a list (ie elements can still be acessed with square bracket, it has a length, etc) but it is not a list.
The iterator xrange is no longer valid in Python 3.
