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 value e to key k.

For example, traditionally, let's update our dictionary so it will contain two more countries:

Country	Area	Population
Brazil	8515767	212559417
India	3166391	1380004385
