Python: Checking if a 'Dictionary' is empty doesn't seem to work
... Sigh ... everybody likes to be "pythonic" and goes for the least characters to type. First, another criteria is readability. Second, the first test in the answer above is true not only if the dict exists and is empty, but also if test_dict is None. So use this test only when you know...
