p010_sort_list_simple

代码：

lista=[20,40,30,50,10]
listb=["bb","ee","aa","dd","cc"]
#lista.sort()
listc=sorted(lista)
listd=sorted(lista,reverse=True)
liste=sorted(listb)
listf=sorted(listb,reverse=True)
print(f"lista is {lista},asc sorted lista is: {listc}")
print(f"lista is {lista},desc sorted lista is: {listd}")
print(f"listb is {listb},asc sorted listb is: {liste}")
print(f"listb is {listb},desc sorted listb is: {listf}")

效果：

lista is [20, 40, 30, 50, 10],asc sorted lista is: [10, 20, 30, 40, 50]
lista is [20, 40, 30, 50, 10],desc sorted lista is: [50, 40, 30, 20, 10]
listb is ['bb', 'ee', 'aa', 'dd', 'cc'],asc sorted listb is: ['aa', 'bb', 'cc', 'dd', 'ee']
listb is ['bb', 'ee', 'aa', 'dd', 'cc'],desc sorted listb is: ['ee', 'dd', 'cc', 'bb', 'aa']

　　

总结：

1. sort()默认是asc排序，desc需要加上reverse=True属性；
2. 复制粘贴的时候注意修改里面对应的内容。
