Not that I know. "The logic is there" in "list(QQ)" but not in "list(ZZ**2)". I remember that there was a jurisprudence somewhere that "all elements of a countable set must have a finite rank in the order of .__iter__()". i.e., that list(ZZ**2) cannot be (0,0), (1,0), (-1,0), (2,0), (-2,0), ...

Hello, By the way, patchbot 2.3.9 is somehow outdated. The latest version can be found at ticket #18937 http://trac.sagemath.org/ticket/18937 (Needs review) I would suggest using this version instead. I am not sure that 2.3.9 will work correctly. Frederic Le mardi 29 septembre 2015 16:06:12

We could just sort vertices/edges in graphviz_string. In the cases where that is a performance problem its unlikely that you can compile the graphviz code anyways. On Tuesday, September 29, 2015 at 4:13:08 PM UTC+2, Jeroen Demeyer wrote: > > Dear graphviz enthousiasts, > > The file src/sage/

[sage-devel] Iterator over product of infinite iterators

2015-09-29 Thread Clemens Heuberger
In #19048, an iterator iterating over the cartesian product of two possibly infinite iterators is needed. This can for instance be implemented by the Cantor pairing function https://en.wikipedia.org/wiki/Pairing_function#Cantor_pairing_function , i.e. the well-known proof that the product of two c

[sage-devel] random output of graphviz_string()

2015-09-29 Thread Jeroen Demeyer
Dear graphviz enthousiasts, The file src/sage/graphs/generic_graph.py has a function graphviz_string() with many doctests. However, these doctests are bad because they depend on implementation details, in particular the order of keys in a dict. This causes serious doctest failures on #19304, wh
