Hi guys,
I have a strange problem that I do not understand. I am testing function
which returns a dictionary. The code should ensure that the keys of the
dictionary are generated in a given order.
I am testing the function with the standard unittest module and use the
assertListEqual statement to verify the sequence. Sometimes this test
fails, sometimes passes without any change neither in the code, nor in the
testcase. I am using "list(myDict.keys())" to create the list of the keys
of the dictionary.
I am running Python 3.3 on MS Windows. Any idea why is this?
Prior to Python 3.6 (de facto) and Python 3.7 (officially), there was no
guarantee at all about the order of keys in a dict. If you need the keys
to be in the same order they were inserted, either use
collections.OrderedDict or upgrade to Python 3.7 or later.
