1、list 列表 python内置的数据类型,有序集合,随时增删。包含的数据类型可以不同:整数、浮点数、字符串、list、tuple、dict、set、bool、空值、常量 list1=[1.2, 2.1, 3, 3.2, 5, 'a', (2, 2, 3), [1.2, 2], {1: 2, 2: 3}, set([2, 3, 2.2]), 3.14, None] 空的列表:list1=[]; li...
元祖转换为列表:tuple-->list list(tuple) append(value)把元素添加到末尾、insert(i,value)把元素添加到任意位置;pop()删除末尾元素、pop(i)删除指定位置的元素、remove(value)直接删除某个元素值;list1.sort()对元素进行排序 取值:list1[0]、list1[4:]、list1[:-4]、list1[2:-3] 嵌套:list里面可以嵌...
you could add new element to both list and tuple with the onlydifference that you will change id of the tuple by adding element(tuple是不可更改的数据类型,这也意味着你不能去删除tuple中的元素或者是对tuple进行排序,然而,你既可以往list里去增加一个新的元素,也可以往tuple里去增加一个新的元素,从...
The main difference between lists and tuples is the fact that lists are mutable whereas tuples are immutable. It means that we can modify a list after it has been initialized i.e. we can add, update or even delete items in a list. But, we cannot change the items in a tuple once i...
1. 获取两个list 的交集 print list(set(a).intersection(set(b))) 2. 获取两个list 的并集 print list(set(a).union(set(b))) 3. 获取两个 list 的差集 print list(set(b).difference(set(a))) # b中有而a中没有的 >>> r=[1,2,3,4,5] ...
map:遍历每个元素,计算并形成一个新的list filter:遍历每个元素,过滤掉不符合条件的元素并形成新的sequence(list to list tuple to tuple) reduce:遍历每个元素,计算并累计最终形成一个数值。 set 元素是不会重复的。基本操作 add remove clear difference(找出对方没有的) issubset issuperset intersection...

前面我们学习了基本数据类型和变量,现在我们学习Python的四种集合,列表(List)和元组(tuple),字典(Dict),无序列表(Set) 一、List(列表) 1、什么是 List (列表) List (列表)是 Python 内置的一种数据类型。是一种有序的集合,可以随时添加和删除其中的元素。 那为什么要有 List (列表)呢? 我们用一个例子来说...
Write a Python program to convert a given list of integers and a tuple of integers into a list of strings. Sample Solution: Python Code : # Create a list named 'nums_list' and a tuple named 'nums_tuple' with integer elementsnums_list=[1,2,3,4]nums_tuple=(0,1,2,3)# Print the...
That also means that you can't delete an element or sort a tuple. However, you could add new element to both list and tuple with the only difference that you will change id of the tuple by adding element(tuple是不可更改的数据类型,这也意味着你不能去删除tuple中的元素或者是对tuple进行排序...
