Tuples (1/3)
Tuples - is one more type of data available in Python. Tuples are usually used when we have a description of some object (such as point coordinates, characteristics of a car, etc...). Tuples may contain data of different types inside, but unlike lists - they are immutable. If you can modify the list by using, for example, list.append() or list.extend(), if you want to modify a tuple, you have to reassign it to a new variable (or the same).
To create tuple use (elem1, elem2, ...) notation or function tuple(x), where x is iterable.
For example, let's create tuple with countries areas and populations.
| Country | Area | Population |
|---|---|---|
| USA | 9629091 | 331002651 |
| Canada | 9984670 | 37742154 |
| Germany | 357114 | 83783942 |
# create tuple countries_tuple = ("USA", 9629091, 331002651, "Canada", 9984670, 37742154, "Germany", 357114, 83783942) print(countries_tuple)
