1. Unpacking

2、enumerate

3、list()

A tuple is an immutable sequence that cannot be modified once created.

1. Unpacking

Take the elements of a tuple and assign them to different variables

>>> a = ('hello', 'world', 1, 2, 3)>>> str1, str2, n1, n2, n3 = a>>> str1'hello'>>> str2'world'>>> n11>>> n22>>> n33>>> str1, str2, *n = a>>> str1'hello'>>> str2'world'>>> n[1, 2, 3]>>> str1, _, n1, n2, _ = a2、enumerate

Explanation: used for tuple traversal, get tuple object, the first element is index, the second is numeric

a = ('1', 2, 35, 'hello')for i in enumerate(a): print(i)>>> (0, '1')>>> (1, 2)>>> (2, 35)>>> (3, 'hello')3、list()

Tuples converted to lists

Pythona =('1 ', 2, 35, ' hello') print(list(a))>> ['1', 2, 35, ' hello'] Thank you for your reading. The above is the content of "How to understand python tuples".
