Here, ‘courses’ is a nested dictionary that contains other dictionary of three elements in each key. There are 2 methods through which we can add keys to a nested dictionary. Ordered dictionaries are just like regular dictionaries but have some extra capabilities relating to ordering operations. Then, we add the key:value pair i.e people[3]['Name'] = 'Luna' inside the dictionary 3. One way to add a dictionary in the Nested dictionary is to add values one be one, Nested_dict[dict][key] = 'value'. A list is a mutable, ordered sequence of items. In nested dictionaries, some keys have another dictionary as its values. Nested Dictionary: Nesting Dictionary means putting a dictionary inside another dictionary. Only the values of a dictionary can be a dictionary because dictionaries are mutable. Strengthen your foundations with the Python Programming Foundation Course and learn the basics. Here, the nested_dict is a nested dictionary with the dictionary dictA and dictB.
