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.
