是一个有序且可变的容器，在里面可以存放多个不同类型的元素
list = [‘阿斯顿‘,‘阿发师‘,‘收发室‘] list = [98,88,66,-1] list = [1,True,‘Alex‘,‘阿萨德‘]
name = ‘ccc‘ data = name.upper() print(name) #ccc print(data) #CCC
append()
list = [‘车子‘,‘妹子‘,‘小子‘] list.append(‘大舅子‘) print(list) #[‘车子‘, ‘妹子‘, ‘小子‘, ‘大舅子‘]
extend()
tools = [‘搬砖‘,‘ 菜刀‘,‘锄头‘] tools.extend([11,22,33]) print(tools) #[‘搬砖‘, ‘ 菜刀‘, ‘锄头‘, 11, 22, 33]
insert()
list = [‘aaa‘,‘bbb‘,‘ccc‘] list.insert(0,‘ddd‘) list.insert(2,‘eee‘) print(list) #[‘ddd‘, ‘aaa‘, ‘eee‘, ‘bbb‘, ‘ccc‘]
remove()
list = [‘aaa‘,‘bbb‘,‘ccc‘,‘ddd‘] list.remove(‘ccc‘) print(list) #[‘aaa‘, ‘bbb‘, ‘ddd‘]
pop()
list = [‘aaa‘,‘bbb‘,‘ccc‘,‘ddd‘] list.pop() print(list) #[‘aaa‘, ‘bbb‘, ‘ccc‘] #当pop不指定索引位置，默认是删除最后一个 list = [‘aaa‘,‘bbb‘,‘ccc‘,‘ddd‘] list.pop(1) print(list) #[‘aaa‘, ‘ccc‘, ‘ddd‘] #当给pop指定索引时，则删除指定索引
clear()
list = [‘aaa‘,‘bbb‘,‘ccc‘,‘ddd‘] list.clear() print(list) #[]
index()
找不到会报错
list = [‘aaa‘,‘bbb‘,‘ccc‘,‘ddd‘] index = list.index(‘ccc‘) print(index) #2
sort()
list = [2,6,8,45,8,3,9,5,1] list.sort() print(list) #[1, 2, 3, 5, 6, 8, 8, 9, 45] list = [2,6,8,45,8,3,9,5,1] list.sort(reverse=True) print(list) #[45, 9, 8, 8, 6, 5, 3, 2, 1] #reverse为True，则是反向排序 list = [‘阿斯顿‘,‘搭嘎上网‘,‘噶文化馆‘,‘高科技为i‘,‘一会就好你‘] list.sort() print(list) #[‘一会就好你‘, ‘噶文化馆‘, ‘搭嘎上网‘, ‘阿斯顿‘, ‘高科技为i‘] #字符串是根据码点来排序的
reverse()
不是排序，而是将列表反向排列
list = [2,6,8,45,8,3,9,5,1] list.reverse() print(list) #[1, 5, 9, 3, 8, 45, 8, 6, 2]
相加
list = [‘阿斯顿‘,‘阿萨德‘] + [‘请问‘,123] print(list) #[‘阿斯顿‘, ‘阿萨德‘, ‘请问‘, 123]
相乘
list = [‘阿斯顿‘,‘阿萨德‘] * 2 print(list) #[‘阿斯顿‘, ‘阿萨德‘, ‘阿斯顿‘, ‘阿萨德‘]
运算符in包含
list = [‘阿斯顿‘,‘阿萨德‘,‘沙雕‘,‘安蓓乐‘] name = ‘沙雕‘ if name in list: print(‘%s在里面‘ % name) else: print(‘%s不在里面‘ % name) #沙雕在里面
获取长度
