Python的元组与列表类似,不同之处在于元组的元素不能修改,元组使用小括号,列表使用方括号,元组创建很简单,只需要在括号中添加元素,并使用逗号隔开即可。本文主要介绍Python 元组(tuple) index() 方法 原文地址: …
tuple built-in function tuple tips: 1.对于Python中的tuple类型来说,他与其它的序列类型来讲最大的不同就是tuple是不可变的。 2.当你需要创建一个只有一个元素的tuple时,需要在元祖分隔符里面加一个逗号(,) 3.tuple只有两个built-in function,一个是count,一个是index。作用和列表类似。这里就不一一赘述了 ...
Index() Method The index() method is a built-in Python function that is used to find the index of the first occurrence of a specified element in a tuple. The method takes a single argument, which is the value to be searched in the tuple. ...
Python >>> int <class 'int'> >>> len <built-in function len> >>> def func(): ... pass ... >>> func <function func at 0x1053abec0> >>> import math >>> math <module 'math' from '.../math.cpython-312-darwin.so'> >>> [int, len, func, math] [ <class 'int'>...

In any Python tuple, the index of the first item is 0, the index of the second item is 1, and so on. The index of the last item is the number of items minus 1. In this example, the tuple has four items, so the last item’s index is 4 - 1 = 3.The number of items in ...
