List - is one of the data structures in Python. It allows storing inside itself variables of different types, such as numbers, strings, tuples, dictionaries... (which will be discussed later).

To create a list, use [] brackets and put inside them variables/values you want to store in the list. Also, you can convert one variable into a list (this variable type has to be iterable, like string, list, or tuple).

For example, we can create a list with countries' names and their population.


              123
            
# create list with countries and their areas
countries = ["USA", 9629091, "Canada", 9984670, "Germany", 357114]
print(countries)

The indexation of elements is the same as for strings, i.e. the very first element has index 0. For example, let's get information about Canada: name is in the third position (which means the index is 2) and area in the fourth (index 3), so we need to write 2:4 (right limit is not inclusive, as you remember).


              123
            
# elements from 2 to 3 in our list
countries = ["USA", 9629091, "Canada", 9984670, "Germany", 357114]
print(countries[2:4])
