Package Ganga :: Package Utility :: Package external :: Module ordereddict :: Class oDict

Class oDict

ordereddict = oDict({'a' : 1, 'b' : 2}, True) The dictionary can be initialised with an optional dictionary passed in as the first argument, You can also pass in an order parameter which chooses the sort method. order=True (default) means all ordered methods use the normal sort function. order=False means all ordered methods use the reverse sort function. order=None means no sort function.

keys, items, iter and pop methods are ordered - based on the key. The ordering is implemented in the keys() function. The iterators are returned using the custom iterator dIter (which will work in three different ways).

pop(self, item=`[]`, default=None)

source code

Emulates the pop method. If item is not supplied it pops the first value in the dictionary. This is different from the normal dict pop method.

fromkeys(cls, args)
Class Method*

source code

Return a new oDict initialised from the values supplied. If sys.version_info > 2.2 this becomes a classmethod.
