append()在列表后面追加元素
lis = ["apple","小米","华为"] lis.append("vivo") print(lis) <<<[‘apple‘, ‘小米‘, ‘华为‘, ‘vivo‘]
insert(index,value)在指定的索引进行添加元素
lis = ["apple","小米","华为"] lis.insert(1,"vivo")# (要添加的索引，内容) print(lis) <<<<[‘apple‘, ‘vivo‘, ‘小米‘, ‘华为‘]
extend()迭代添加，在后面追加
lis = ["apple","小米","华为"] lis1 = ["apple","小米","华为"] a = "123456" lis.extend(a) # 迭代添加,字符串里的每个字符进行迭代添加 print(lis) <<<<[‘apple‘, ‘小米‘, ‘华为‘, ‘1‘, ‘2‘, ‘3‘, ‘4‘, ‘5‘, ‘6‘] lis1.extend([a]) # 将字符串一整个进行添加 print(lis1) <<<<[‘apple‘, ‘小米‘, ‘华为‘, ‘123456‘]
pop(index) 如果里面没有值就是默认删除列表最后一个，不能多次删除，下一次删除的索引值会在上一次删除后进行重新分配
lis = ["apple","小米","华为"] lis.pop(0) # 这里删的是"apple" print(lis) <<<<[‘小米‘, ‘华为‘] lis.pop(1) # 这里删的是"华为" print(lis) <<<<[‘小米‘]
remove("")指定删除
lis = ["apple","小米","华为"] lis.remove("apple") print(lis) <<<<[‘小米‘, ‘华为‘]
del list(index:index)切片删除
lis = ["apple","小米","华为"] del lis[0:1] # 删掉了"apple" print(lis) <<<<[‘小米‘, ‘华为‘]
clear()清空列表
lis = ["apple","小米","华为"] lis.clear() # 清空列表 print(lis) <<<<[] # 空的列表
通过列表索引进行更改
lis = ["apple","小米","华为"] lis[0]="1234" # 通过索引改 print(lis) # <<<< [‘1234‘, ‘小米‘, ‘华为‘]
sort()列表数字排序，默认升序
li = [23,55,34,77,37,99,11,3,6,31] li.sort() # 默认升序 print(li) <<<<[3, 6, 11, 23, 31, 34, 37, 55, 77, 99]
sort(reverse=True) 降序
li.sort(reverse=True) # 降序 print(li) <<<<[99, 77, 55, 37, 34, 31, 23, 11, 6, 3]
reverse()翻转列表翻转180度
lis = ["apple","小米","华为"] lis.reverse() print(lis) <<<< [‘华为‘, ‘小米‘, ‘apple‘]
