Скачать или смотреть #3. Python Introduction to Lists

In this video and the next you’ll learn
what lists are and how to start working with
the elements in a list.

What are lists?
A list is a collection of items in a particular order. You can make a list that
includes the letters of the alphabet, the digits from 0–9, or the names of
all the people in your family. Lists are
one of Python’s most powerful features readily accessible to new programmers, and they tie together many
important concepts in programming.
