Python Lists
To create a list, place comma-separated values inside square brackets [], or convert an iterable (like a string, set, or tuple) using list(). For example, you can create a list with details about the USA (country name, land area, and population).
12345# Creating list information = ["USA", 9629091, 331002651] # Printing list print(information)
Accessing list elements is similar to accessing characters in a string. You can do this using indexing and slicing.
To retrieve the land area and population from US_Info, target the second (index 1) and third (index 2) items. Use slicing with a colon : to specify the start and end positions. The upper limit of a slice is excluded, so use [1:3] to retrieve these two elements.
12345# Getting area and population information = ["USA", 9629091, 331002651] # Printing list print(information[1:3])
