OrderedDict Dict
Good at reordering operations Good at mapping operations
Space efficiency, iteration speed, and the performance of update operations were secondary Tracking insertion order was secondary.
OrderedDict has a move_to_end() method to efficiently reposition an element to an endpoint That feature is not available in dict
reversed() function is supported Not supported till python version 3.8
Equality operation checks for matching order Mappings (instances of dict) compare equal if and only if they have equal (key, value) pairs
popitem() accepts optional argument to specify which item to be popped popitem() removes and returns the last inserted item(key,value) from the dictionary.
