There is some kind of sorting with ``pretty``: https://github.com/ipython/ipython/blob/master/IPython/lib/pretty.py#L124 However, this does not seem to be used with frozensets (but I did not study the code very carefully, how pretty printing works). It seems that they try sorting and if it fails use the string representations as keys. (which would work fine in this particular situation). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
