That should only process the first dict in the list, due to a misplaced return. > roundingVals_toTwoDeci(y) > j = json.dumps(y) > print j > > //At this point, print j gives me > > [{"a": 80.0, "b": 0.0, "c": 10.0, "d": 10.0}, {"a": 100.0, "b": 0.0, "c": > [{0.0, "d": 0.0}, {"a": > 80.0, "b": 0.0, "c": 10.0, "d": 10.0}, {"a": 90.0, "b": 0.0, "c": 0.0, > "d": 10.0}] > > //then I do, > params = urllib.urlencode({'thekey': j}) > > //I then decode params and print it and it gives me > > thekey=[{"a": 80.0, "b": 0.0, "c": 10.0, "d": 10.0}, {"a": 100.0, "b": > 0.0, "c": 0.0, "d": 0.0}, {"a": 80.0, "b": 0.0, "c": 10.0, "d": 10.0}, > {"a": 90.0, "b": 0.0, "c": 0.0, "d": 10.0}] > > However, at the URL, the values show up as 90.000043278694123 Can you give the actual code, including the decoding part? Preferably you'd put both encoding and decoding into one small self-contained demo script. -- https://mail.python.org/mailman/listinfo/python-list
