ExampleGet your own Python Server Create a dictionary that contain three dictionaries: myfamily = { "child1": { "name":"Emil", "year":2004 }, "child2": { "name":"Tobias", "year":2007 }, "child3": { "name":"Linus
In the above program, we create an empty dictionary3inside the dictionarypeople. Then, we add thekey:valuepair i.epeople[3]['Name'] = 'Luna'inside the dictionary3. Similarly, we do this for keyage,sexandmarriedone by one. When we print thepeople[3], we getkey:valuepairs of dictiona...
We can also add elements as we do in a normal Python dictionary. Moreover, we can also add a whole dictionary as an element. For example: d1={0:{"Dept":"Mathematics","Prof":"Dr Jack"},1:{"Dept":"Physics","Prof":"Dr Mark"},}d1[2]={"Dept":"CS","Prof":"Dr Jay"}print...
