Tuples (2/3)
But you might be wondered - why do we there use tuples instead of lists? Yes, now it makes no difference, but remember, that tuple is immutable, so it is better in terms of memory. But as for now, we shouldn't pay attention to this, as we work with small data.
You can refer to elements inside the tuple the same way as for lists. But at the same time, you can't simply append an element to your tuple, as you need to "rewrite" it.
len()- length of tuple (number of elements);tuple1 + tuple2- concatenation (both must be tuples);tuple1 * n- n copies of tuple1;tuple1.count(x)- counts number of x in tuple1.
For example, let's modify our tuple with new information:
| Country | Area | Population |
|---|---|---|
| Brazil | 8515767 | 212559417 |
| India | 3166391 | 1380004385 |
Pay attention, that for concatenation both must be tuples!
1234567# old countries tuple countries_tuple = ("USA", 9629091, 331002651, "Canada", 9984670, 37742154, "Germany", 357114, 83783942) # new information new_data = ("Brazil", 8515767, 212559417, "India", 3166391, 1380004385) # create new updated tuple and print it upd_countries = countries_tuple + new_data print(upd_countries)
