3.1 list

In python, square brackets [] are used to represent the list and commas are used to separate the elements.

bicycles = [‘trek‘, ‘cannondale‘, ‘redline‘, ‘specialized‘]print(bicycles)

[‘trek‘, ‘cannondale‘, ‘redline‘, ‘specialized‘]

3.1.1 access list elements

bicycles = [‘trek‘, ‘cannondale‘, ‘redline‘, ‘specialized‘]print(bicycles[0])

trek

bicycles = [‘trek‘, ‘cannondale‘, ‘redline‘, ‘specialized‘]print(bicycles[0].title())

Trek

3.1.2 index starts from 0 instead of 1

These codes return the second and fourth elements in the list.

bicycles = [‘trek‘, ‘cannondale‘, ‘redline‘, ‘specialized‘]print(bicycles[1])print(bicycles[3])

cannondalespecialized

Python provides a special syntax for accessing the last list element. By specifying the index as-1, python can return the last list element:

bicycles = [‘trek‘, ‘cannondale‘, ‘redline‘, ‘specialized‘]print(bicycles[-1])

specialized
