Tuple is an indexed data structure like array, in similar fashion we can access the elements of tuple using [] operator, index starts from ‘0’. And it will throw an error if code try to access tuple beyond its range Element : 3 5 7 11 13 19 Index : 0 1 2 3 4 5 Accessing fr...
# 定义元组my_tuple=(1,"apple",True,3.14,[5,6,7],{"name":"TiYong","age":25})# 使用索引访问单个元素first_element=my_tuple[0]# 第一个元素print("第一个元素:",first_element)second_element=my_tuple[1]# 第二个元素print("第二个元素:",second_element)last_element=my_tuple[-1]# 最...
The example above defines a tuple my_tuple with elements 1, 2, ‘a’, ‘b’, True, and. We can access individual elements of the tuple using indexing, just like lists. However, if we try to change an element of the tuple, it will return an error because tuples are immutable. Usual...
my_tuple = (1, 2, 3) #create tuple print(my_tuple) 输出: (1,2,3) 访问元素 访问元素与访问列表中的值相同。 my_tuple2 = (1, 2, 3, 'python') #access elements for x in my_tuple2: print(x) print(my_tuple2) print(my_tuple2[0]) print(my_tuple2[:]) print(my_tuple2[3][...
my_tuple=(1,'apple',3.14)first_element=my_tuple[0]# 1second_element=my_tuple[1]# 'apple' 切片操作也可以用于获取元组的一部分: slice_of_tuple=my_tuple[1:3]# ('apple', 3.14) 2.3 元组的长度 要获取元组的元素个数,可以使用内置的 len() 函数: ...
my_tuple[0]=10# TypeError: 'tuple' object does not support item assignment # 可以重新赋值my_tuple=(10,'apple') 3. 集合(set) 集合是一个无序的不重复元素序列 集合用方括号{}表示,元素之间用逗号,分隔 3.1 创建集合 方式一:set_name = {element1, element2, ..., elementn} ...
To sort a list of tuples by the first element in Python, you can use the built-insorted()function along with a lambda function as the key. For example, given a list of tuplesemployees = [(104, 'Alice'), (102, 'Bob'), (101, 'Charlie'), (103, 'David')], you can sort it...
>>> tn[4][0]#Access a nested tuple5 您还可以从称为打包的过程的一组现有变量中创建一个tuple。 反之亦然,其中,tuple中的值被指派给变量。这之后的过程称为解包,它是用于许多情形的功能十分强大的技术,其中包括希望从一个函数中返回多个值。在解包tuple时,仅有的问题是必须为tuple中的每个数据项提供一个...
Challenge yourself with this quiz to evaluate and deepen your understanding of Python lists and tuples. You'll explore key concepts, such as how to create, access, and manipulate these data types, while also learning best practices for using them efficiently in your code.Getting...
Indexing of Tuples in Python To access an element of a tuple, we simply use the index of that element. We use square brackets around that index number as shown in the example below: tup1 = (‘Intellipaat’, ‘Python’, ‘tutorial’) print (tup1[0]) Output: Intellipaat Learn more...
