Just noted, too, that the first example of producing a dict can be eliminated in favor of the second:
>>> roots((x - 1)**2*(x - 2), x) # Some functions return dicts {1: 2, 2: 1} >>> # Some SymPy functions return dictionaries. For example, >>> # roots returns a dictionary of root:multiplicity items. >>> roots((x - 5)**2*(x + 3), x) {-3: 1, 5: 2} -- You received this message because you are subscribed to the Google Groups "sympy" group.
