In Python, to iterate the dictionary object dict with a for loop, use keys(), values(), items().You can also get a list of all keys and values in the dictionary with list().. Iterate keys of dict: keys(); Iterate values of dict: values(); Iterate key-value pairs of dict: items(); Take the following dictionary as an example. >>> D1 = {1:'a', 2:'b', 3:'c'} >>> for k in D1.keys(): print (k, D1[k]) 1 a 2 b 3 c. There is also items () method of dictionary object which returns list of tuples, each tuple having key and value. In Python, a nested dictionary is a dictionary inside a dictionary.
