python初始化list列表（1维、2维）
python初始化list列表（1维、2维）1.初始化递增的list：list1 = range(10)#print list1#[0,1,2, (9)2.初始化每项为0的⼀维数组：list2 = [0] * 5#print list2#[0,0,0,0,0]3.初始化固定值的⼀维数组：initVal = 1listLen = 5list3 = [ initVal for i in range(5)]#print list3#[1,1,1,1,1]list4 = [initVal] * listLen#print list4#[1,1,1,1,1]4.初始化⼀个5x6每项为0（固定值）的数组（推荐使⽤）：multilist = [[0 for col in range(5)] for row in range(6)]5.初始化⼀个5x6每项为0（固定值）的数组multilist = [[0] * 5 for row in range(3)]看到了以上的⽅法，那初始化⼀个⼆维数组时，是否可以这样做呢：multi = [[0] * 5] * 3其实，这样做是不对的，因为[0] * 5是⼀个⼀维数组的对象，* 3的话只是把对象的引⽤复制了3次，⽐如，我修改multi[0][0]：multi = [[0] * 5] * 3multi[0][0] = 'Hello'print multi输出的结果将是：[['Hello', 0, 0, 0, 0], ['Hello', 0, 0, 0, 0], ['Hello', 0, 0,0, 0]]我们修改了multi[0][0]，却把我们的multi[1][0]，multi[2][0]也修改了。
这不是我们想要的结果。
但是如下写法是对的：multilist = [[0] * 5 for row in range(3)]multilist[0][0] = 'Hello'print multilist我们看输出结果：[['Hello', 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0]]恩，没问题。

python中列表list的用法
python中列表list的用法一、什么是列表？列表是Python中的内置数据类型，它由一系列具有相同类型的元素组成，列表中的元素可以是任何类型。
它们可以是字符串、数字或其他列表。
二、列表的创建方式1、使用方括号：list1 = []此时list1就是一个空列表。
2、使用list关键字：list2 = list()此时list2也是一个空列表。
3、通过拼接：list3 = [1, 2, 3] + [4, 5, 6]此时list3的元素为1，2，3，4，5，6。
三、Python中的列表操作1、访问列表中的元素：列表的索引从0开始，可以通过索引来访问列表中的元素，例如： fruit = ['apple', 'banana', 'cherry']apple = fruit[0]banana = fruit[1]cherry = fruit[2]2、更新列表中的元素：可以通过指定索引来更新列表中的元素，例如：fruit = ['apple', 'banana', 'cherry']fruit[0] = 'mango'此时fruit中的第一个元素变为mango。
3、删除列表中的元素：可以使用del关键字来删除列表中的元素，例如：fruit = ['apple', 'banana', 'cherry']del fruit[0]此时apple就被删除，fruit中只剩下banana和cherry。
四、Python中的列表函数1、len()函数：len()函数可以用来获取列表中元素的个数，例如：fruit = ['apple', 'banana', 'cherry']num = len(fruit)此时num的值为3，即fruit中元素的个数为3。

listutils常用方法
listutils常用方法
listutils是一个常用的Python库，为了方便大家使用，本文将介绍listutils常用方法，包括列表的合并、排序、查找、删除等基本操作。
一、列表的合并
1.1 extend()：将一个列表里的所有元素添加到一个列表中。
list1 = [1, 2, 3]
list2 = [4, 5, 6]
list1.extend(list2) # [1, 2, 3, 4, 5, 6]
1.2 + : 将两个列表合并为一个列表。
二、列表的排序
2.1 sort()方法：对列表进行排序。
三、列表的查找
3.1 index()方法：查找列表中某个元素的位置。
四、列表元素的删除
4.1 pop()方法：用于移除列表中的一个元素，并返回该元素的值。
4.3 del关键字：用于删除列表中指定位置的元素。
以上就是listutils库中一些常用的方法，熟练掌握这些方法可以让我们更加方便、高效的使用Python来处理列表。

遍历list 2次循环的结果拼接
遍历list 2次循环的结果拼接遍历list是一种常见的数据操作，它可用于访问列表中的每个元素，并对其进行处理。
遍历列表可以通过循环来实现，而循环可以使用不同的控制结构，如for循环和while循环。
在这篇文章中，我们将探讨遍历列表两次循环的结果拼接。
首先，我们需要了解什么是列表。
列表是Python中一种常用的数据类型，它用于存储一系列有序的元素。
列表中的元素可以是任何类型的数据，例如整数、字符串、浮点数等。
列表中的元素是通过索引访问的，索引从0开始计数。
那么什么是遍历列表呢？遍历列表就是按照顺序访问列表中的每个元素，并对其进行操作或处理。
遍历列表可以使用for循环完成，如下所示：```my_list = [1, 2, 3, 4, 5]for element in my_list:#处理每个元素print(element)```上述代码中，我们定义了一个列表my_list，并使用for循环遍历该列表。
在每次迭代中，元素被赋值给变量element，我们可以对element进行进一步的处理。
现在，我们来探讨遍历列表两次循环的结果拼接。
假设我们有两个列表list1和list2，我们希望将这两个列表依次遍历，并将结果拼接起来。
为了达到这个目的，我们可以使用两层嵌套的循环，如下所示：```pythonlist1 = [1, 2, 3]list2 = ['a', 'b', 'c']result = []for i in list1:for j in list2:result.append(str(i) + j)print(result)```上述代码中，我们定义了两个列表list1和list2，并创建一个空列表result用于存储结果。
然后，我们使用两层嵌套的for循环，遍历list1和list2中的每个元素。
在每次迭代中，我们将list1中的元素和list2中的元素进行拼接，并将结果添加到result列表中。
python中list的用法
python中list的用法
Python中list是一种有序的集合，可以容纳任意类型的数据，可以使用索引来访问list 中的元素。
1. 创建list：
使用方括号[]来创建list，例如：
```
list1 = [1, 2, 3, 4, 5]
list2 = ["a", "b", "c", "d"]
```
2. 访问list中的元素：
使用索引来访问list中的元素，例如：
```
list1[0] # 访问list1中的第一个元素
list2[3] # 访问list2中的第四个元素
```
3. 修改list中的元素：
使用索引来修改list中的元素，例如：
```
list1[2] = 10 # 修改list1中第三个元素为10
list2[1] = "x" # 修改list2中第二个元素为x
```
4. 删除list中的元素：
使用del语句来删除list中的元素，例如：
```
del list1[1] # 删除list1中的第二个元素
del list2[2] # 删除list2中的第三个元素
```
5. 获取list的长度：
使用len()函数来获取list的长度，例如：
```
len(list1) # 获取list1的长度
len(list2) # 获取list2的长度
```
6. 合并list：
使用+号来合并两个list，例如：
```
list3 = list1 + list2 # 合并list1和list2 ```。
list的用法
list的用法
list是Python中的列表类型，是用来存放任何类型的有序数据的容器。
它可以容纳不定量的数据，包括字符串、数字、元组和其他容器类型。
list的列表元素也可以是不同的类型，比如字符串和数字。
list的使用：
1、创建list：可以使用[]，例如： list1 = [1, 2, 3, 4]
2、添加元素：可以使用append和extend方法，例如： list1.append('5') 或 list2.extend(list1)
3、删除元素：可以使用remove和pop方法，例如：list1.remove('5') 或list1.pop(2)
4、访问元素：可以使用索引和循环控制，例如：list1[2] 或 for item in list1:
5、修改元素值：可以使用索引，例如：list1[2] = '6'
6、排序：可以使用sort or sorted方法，例如：list1.sort() 或 sorted(list2)
7、移动元素：可以使用insert方法，例如：list1.insert(3, '7')
8、求和：可以使用sum方法，例如：sum(list1)
9、求最大值：可以使用max方法，例如：max(list1)
10、求最小值：可以使用min方法，例如：min(list1)
list是Python中非常常见的数据类型，应用广泛，可以满足复杂的数据结构和复杂的数据操作需求。
它有灵活的数据操作、高性能的存储能力。
我们可以用很少的代码来实现比较复杂的数据结构和数据操作，可以极大的提高开发效率和节省开发时间。
