排序：sorted()显示临时排序cars = ['byd','audi','gelly','qirui','chengcheng']
print(sorted(cars))
print(cars)结果：['audi', 'byd', 'chengcheng', 'gelly', 'qirui']['byd', 'audi', 'gelly', 'qirui', 'chengcheng']sort() 对列表排序并改变原序列cars = ['byd','audi','gelly','qirui','chengcheng']
print(cars.sort())
print(cars)结果：None['audi', 'byd', 'chengcheng', 'gelly', 'qirui']注意：cars.sort()不返回结果。使用sort()方法reverse=True 倒序排列:cars = ['byd','audi','gelly','qirui','chengcheng']
cars.sort(reverse=True)
print(cars)结果：['qirui', 'gelly', 'chengcheng', 'byd', 'audi']使用sorted()方法reverse=True 倒序排列:cars = ['byd','audi','gelly','qirui','chengcheng']
print(sorted(cars,reverse=True))
print(cars)结果：['qirui', 'gelly', 'chengcheng', 'byd', 'audi']['byd', 'audi', 'gelly', 'qirui', 'chengcheng']反转列表（不排序仅反转列表的顺序）：reverse()cars = ['byd','audi','gelly','qirui','chengcheng']
cars.reverse()
print(cars)结果：['chengcheng', 'qirui', 'gelly', 'audi', 'byd']遍历列表：for循环cars = ['byd','audi','gelly','qirui','chengcheng']

列表合并
加号：
cars = ['byd','audi','gelly','qirui','chengcheng']
planes = ['boyin','shenfei','chengfei']
carsAndPlanes = cars + planes
print(carsAndPlanes)结果：
['byd', 'audi', 'gelly', 'qirui', 'chengcheng', 'boyin', 'shenfei', 'chengfei']
extend()方法：
cars = ['byd','audi','gelly','qirui','chengcheng']
planes = ['boyin','shenfei','chengfei']
# carsAndPlanes = cars.extend(planes)
cars.extend(planes)
print(cars)结果：
['byd', 'audi', 'gelly', 'qirui', 'chengcheng', 'boyin', 'shenfei', 'chengfei']
注意：cars.extend(planes)不能返回结果。
使用切片，将一个列表插入另一个列表：
cars = ['byd','audi','gelly','qirui','chengcheng']
planes = ['boyin','shenfei','chengfei']
cars[len(cars):len(cars)]=planes
print(cars)结果：
['byd', 'audi', 'gelly', 'qirui', 'chengcheng', 'boyin', 'shenfei', 'chengfei']
注意：语法形式如下:
list1[len(list1):len(list1)] = list2
len(list1) 代表将list2插入list1中的位置
