#Python's container iteration

Tuples, lists, dictionaries, and sets are all iterable objects, and their elements can be accessed one by one using a for loop:

#Tuple

Iterating through elements in a tuple:

students:tuple[str, str, str] = ("Tom", "Jerry", "Spike")
for student in students:
    print(student)

#Dictionary

Iterating through a dictionary yields keys by default:

score_list:dict[str,int] = {
    'Tom': 88,
    'Jerry': 99,
    'Spike': 66
}
for key in score_list:
    print(key, score_list[key])

#Set

Iterating through elements in a set:

fruits:set[str] = {'Apple', 'Orange', 'Strawberry', 'Banana', 'Pineapple'}
for fruit in fruits:
    print(fruit)

#String

A string is also an iterable object, which yields characters one by one:

text:str = "hello world"
for word in text:
    print(word)
