cars = ['bmw', 'audi', 'toyota', 'subaru']
cars.sort() # 永久修改列表元素的排序，现在是按照字母排序的
print(cars)
cars.sort(reverse=True) # 永久修改列表元素的排序，reverse是反转排列 虽然是永久性修改 但可以再次使用reverse恢复原来排序
print(cars)
# sorted() 是临时排序，允许修改
cars_1 = ['bmw', 'audi', 'toyota', 'subaru']
print("Here is the original list:")
for i in cars_1:
print(i.title())
continue
print(len(cars_1))
print("\nHere is the sorted list:")
print(sorted(cars_1))
print("\nHere is the original list again:")
print(cars_1)
练习
Want_Togo = ['Japan', 'American', 'Egypt', 'Australia', 'France']
print(sorted(Want_Togo))
print(Want_Togo)
Want_Togo.reverse() # 反转
print(Want_Togo)
Want_Togo.reverse() # 再次反转
print(Want_Togo)
Want_Togo.sort() # 按字母排序
print(Want_Togo)
