2、查找某个元素对应的下标索引 - index 函数 调用tuple#index 函数 , 可以查找 元组 中指定元素 对应的下标索引 ; 函数原型如下 : 代码语言:javascript 代码运行次数:0 运行 AI代码解释 defindex(self,*args,**kwargs):# real signature unknown""" Return first indexofvalue.Raises ValueErrorifthe value is...
Example 1: Python Tuple index() # tuple containing vowelsvowels = ('a','e','i','o','i','u') # index of 'e' in vowelsindex = vowels.index('e') print('Index of e:', index) # index of the first 'i' is returnedindex = vowels.index('i') ...
You can access individual elements in a list or tuple using the item’s index in square brackets. This is exactly analogous to accessing individual characters in a string. List indexing is zero-based, as it is with strings.Consider the following list:...
tup = tuple("Python") print(tup[0]) # "P" 1. 2. 当访问的索引值超过元组的最大索引值时就会抛出异常 tup = tuple("Python") print(tup[6]) # IndexError: tuple index out of range 1. 2. 3. 2. 切片操作 列表可以进行切片截取操作。
调用tuple#index 函数 , 可以查找 元组 中指定元素 对应的下标索引 ; 函数原型如下 : AI检测代码解析 def index(self, *args, **kwargs): # real signature unknown """ Return first index of value. Raises ValueError if the value is not present. ...
`python my_string = "hello" my_tuple = tuple(my_string) print(my_tuple) 2. 元组的解构赋值 `python my_tuple = (1, 2, 3) a, b, c = my_tuple print(a, b, c) 3. 元组作为函数的返回值 `python def get_coordinates(): x = 10 ...
Python 列表、元组、字典及集合操作 python容器 注意:当索引超出范围时,Python会报一个IndexError错误,所以,要确保索引不要越界,记得最后一个元素的索引是len(list1) - 1。 py3study 2020/01/19 1.5K0 python list tuple d copyddddefaultkeylist name = ["aaa","bbb","ccc","ddd","eee","fff","ggg...

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: …
num_tuple = (1, 3, 7, 8, 7, 5, 4, 6, 8, 5, 5) print(num_tuple.index(999)) 如果未找到该值,index() 方法将引发异常,ValueError: tuple.index(x): x not in tuple。 5、总结 以上就是本文的全部内容啦!如果对您有帮助,麻烦点赞啦!收藏啦!欢迎各位评论区留言!!!
