To create a tuple with a single element, you have to include a final comma(创建一个只有1个元素的元组,必须以"逗号"结尾): >>> t1 ='a',>>>type(t1)<type'tuple'> A value in parentheses is not a tuple: >>> t2 = ('a')>>>type(t2)<type'str'> Another way to create a tuple i...
Create a Python Tuple With One Item When we want to create a tuple with a single item, we might do the following: var = ('Hello')print(var)# string Run Code But this would not create a tuple; instead, it would be considered astring. To solve this, we need to include a trailing ...
single_element_tuple=(1,)# 注意:单个元素的元组需要在元素后面添加逗号 三,元组的常见操作方法 1,下标索引 (1)常规下标索引 元组的下标索引和列表基本无异,同样可以使用正向或反向索引 示例: 代码语言:javascript 代码运行次数:0 复制 Cloud Studio代码运行 my_tuple=(1,2,3,4,5)# 使用正向索引print(my_tu...
Create atuplevariable with a single element. MATLAB displays a trailing comma for atuplewith one element. subject = py.tuple({'Biology'}) subject = Python tuple with values: ('Biology',) Use string, double or cell function to convert to a MATLAB array....
my_tuple=(1,2,3,4,5) 创建空元组: empty_tuple=() 创建只包含一个元素的元组: single_element_tuple=(42,) Notes:这里在元素后面加上逗号,是为了以区分它与普通的表达式不同,不加的话,这里就是括号运算。 3.访问元组 在Python中,元组(tuple)可以通过索引和切片来访问其中的元素。索引从 0 开始,一直到...
empty_tuple=() 2.1.2 单元素元组 单元素元组需要在元素后面加上逗号,以避免与普通括号表达式混淆: single_element_tuple=(1,) 2.1.3 多元素元组 多元素元组由逗号分隔的任意数量的元素组成: multiple_elements_tuple=(2,'b',3.14159,[4,5]) 2.2 访问元组元素 ...
python-tuple : 可认为是不可变的列表,一般用来保存无需修改的内容 元组中的元素不可修改!!! 一、定义: (element1,element2,..., elementn) 元组可以用来存储整数,实数,字符串,列表,元组 a=('string','abc','123') b=('string',123) c=('abc',['123','abc',11],123)...
