[Python] Difference between dictionary and OrderedDict

I am trying to get a sorted dictionary. But the order of the items between mydict and orddict doesn't seem to change.

from collections import OrderedDict

mydict = {'a': 1, 'b': 2, 'c': 3, 'd': 4}

orddict = OrderedDict(mydict)

print(mydict, orddict)

print('mydict')
for k, v in mydict.items():
print(k, v)

print('ordereddict')
# print items in ordered dictionary
