Create a list of names
commander_names = ["Alan Brooke", "George Marshall", "Frank Jack Fletcher", "Conrad Helfrich", "Albert Kesselring"]
Sort Alphabetically By Last Name
To complete the sort, we will combine three operations:
lambda x: x.split(" "), which is a function that takes a string
xand breaks it up along each blank space. This outputs a list.
[-1], which takes the last element of a list.
sorted(), which sorts a list.
# Sort a variable called 'commander_names' by the last elements of each name. sorted(commander_names, key=lambda x: x.split(" ")[-1])
['Alan Brooke', 'Frank Jack Fletcher', 'Conrad Helfrich', 'Albert Kesselring', 'George Marshall']
