bookTuples (3/3)

Like for lists, you can place tuples inside tuples! And then you can use double indexing to reach the element in tuple inside a tuple.

For example, for out five countries

Canada998467037742154
Germany35711483783942

# create two-dimensional tuple
two_d_countries = (('USA', 9629091, 331002651), ('Canada', 9984670, 37742154), 
                   ('Germany', 357114, 83783942), ('Brazil', 8515767, 212559417), ('India', 3166391, 1380004385))
# information about India
print(two_d_countries[4])
# area of Canada
print(two_d_countries[1][1])
copy
