If we want the first item of extinct_birds, we can extract it from all_birds by specifying two indexes: >>> all_birds[1][0] 'dodo' Mutable types (lists, dictionaries, and sets) have comprehensions. Immutable types like strings and tuples need to be created with the other methods liste...
The itertools.combinations() function takes two arguments—an iterable inputs and a positive integer n—and produces an iterator over tuples of all combinations of n elements in inputs.For example, to list the combinations of three bills in your wallet, just do:...

Note: You should keep in mind that individual members of enums based on IntFlag, also known as flags, should take values that are powers of two (1, 2, 4, 8, …). However, this isn’t a requirement for combinations of flags, like Role.ADMIN. In the above example, you defined Role...
