Dictionaries (2/2)
Let's consider some useful methods for dictionaries:
len(d)- returns length of dictionary d (number of pairs key:value);min(d), max(d)- minimum or maximum of keys of dictionary d;d.copy()- returns copy of dictionary d;d.items()- returns all pairs (key, value) in dictionary d;d.keys()- returns all keys of dictionary d;d.values()- returns all values of dictionary d;d[k] = e- set valueeto keyk.
For example, traditionally, let's update our dictionary so it will contain two more countries:
| Country | Area | Population |
|---|---|---|
| Brazil | 8515767 | 212559417 |
| India | 3166391 | 1380004385 |
123456# old dictionary countries_dict = {'USA': (9629091, 331002651), 'Canada': (9984670, 37742154), 'Germany': (357114, 83783942)} # update dictionary with countries countries_dict["Brazil"] = (8515767, 212559417) countries_dict["India"] = (3166391, 1380004385) print(countries_dict)

Update your dictionary with people so it will contain information for the next two people and then print the whole dictionary:
| Name | Age | Height |
|---|---|---|
| John | 41 | 185 |
| Michelle | 35 | 165 |
