Of course there are strings, int too. I'm listing this here as I often forget these: List Somewhat similar to tuple (see below) but changeable. Uses square brackets instead of parenthesis in tuple. 1>>> kirk = ["James Kirk", 34, "Captain", 2265] 2>>> type(kirk) 3<class 'list'> Tuple A tuple is a collection which is ordered and unchangeable. 1>>> mytuple = ("apple", "banana", "cherry") 2>>> type(mytuple) 3<class 'tuple'> Dictionary 1>>> comedian = {'name': 'Eric Idle', 'age': 74} 2>>> type(comedian) 3<class 'dict'> 4>>>https://quicktasks.ismael.casimpan.com/post/pythonic-code-using-enumerate/Sat, 12 Feb 2022 00:20:25 +0800https://quicktasks.ismael.casimpan.com/post/pythonic-code-using-enumerate/ Use enumerate to iterate to each list's element 1>>> # Pythonic Example 2>>> animals = ['cat', 'dog', 'moose'] 3>>> for i, animal in enumerate(animals): 4... print(i, animal) 5... 60 cat 71 dog 82 moose If the index is not important, use "_" in place of "i": 1>>> # Pythonic Example 2>>> animals = ['cat', 'dog', 'moose'] 3>>> for _, animal in enumerate(animals): 4... print(animal) 5... 6cat 7dog 8moose Or more simply, without using "enumerate" function:
