i just tried something with solving a equation, i think i did it the wrong way, but still it should not result in this:
def calc_wights_by_sum(s) variables = var(["w" + str(i) for i in range(s.nvertices())]) equation = reduce(lambda f1,f2: f1 + f2, [variables[i] * s.vertex(i) for i in range(s.nvertices())]) == 0 print equation return solve(equation,variables) sage: calc_wights_by_sum(s) False Exception RuntimeError: 'maximum recursion depth exceeded in __subclasscheck__' in <type 'exceptions.RuntimeError'> ignored Exception RuntimeError: RuntimeError('maximum recursion depth exceeded in cmp',) in Exception RuntimeError: 'maximum recursion depth exceeded in __subclasscheck__' in <type 'exceptions.RuntimeError'> ignored ignored Exception RuntimeError: 'maximum recursion depth exceeded in __subclasscheck__' in <type 'exceptions.RuntimeError'> ignored Exception RuntimeError: RuntimeError('maximum recursion depth exceeded in cmp',) in Exception RuntimeError: 'maximum recursion depth exceeded in __subclasscheck__' in <type 'exceptions.RuntimeError'> ignored [...] i just helped to kill python by killall -9 python. greatz Johannes -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
