Sort keys in the python3.0 Dictionary

The dictionary object is actually the addition, modification, and deletion of the dictionary object below the key-value pair (the modification is the same as the addition method and is added when the key value does not exist) IDLE 3.0
>>> Dic = {"aa": 1, "bb": 2, "AB": 3}
>>> Dic
{'A': 1, 'AB': 3, 'BB': 2}
>>> For k in sorted (dic. keys ()):
Print (k)

Aa
AB


-----------------------------------------------
The dictionary object is actually a key-value pair.
The following describes how to add, modify, and delete dictionary objects.
(The modification is the same as the addition method. if the key value does not exist, add it)
>>> Dic ["cc"] = 4
>>> Dic
{'A': 1, 'CC': 4, 'AB': 3, 'BB': 2}
>>> Dic ["bc"] = 5
>>> Dic
{'A': 1, 'CC': 4, 'AB': 3, 'BB': 2, 'BC': 5}
>>> Dic ["cc"] = 6
>>> Dic
{'A': 1, 'CC': 6, 'AB': 3, 'BB': 2, 'BC': 5}
>>> Del dic ["cc"]
>>> Dic
{'A': 1, 'AB': 3, 'BB': 2, 'BC': 5}
