Lists

Lists are good for keeping track of things by their order, especially when that order might change.

• Lists are mutable; you can add new elements, and modify or delete existing ones
• A list is made of zero or more elements separated by commas, and surrounded by square brackets
• The same value can occur more than once in a list
• Lists can contain elements of different types, including other lists
• To create a list you can use [] or the list() function

# returns []

empty_list = []

# returns []

another_empty_list = list() 

# returns ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']

weekdays = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']

List Type Conversion

To change other Python data types to a list, use the list() function. The following example converts a string to a list of one-character strings.

# returns  ['s', 'u', 'n', 's', 'h', 'i', 'n', 'e']

list('sunshine')
