students = ['Alice', 'Bob', 'Candy', 'David', 'Ellena']

自己写代码:

结果：

[99, 89, 88, 79, 72]
['Ellena', 'Alice', 'Candy', 'David', 'Bob']

代码:

names = ['Alice', 'Bob', 'Candy', 'David', 'Ellena']

scores = [89, 72, 88, 79, 99]

for i in range(len(scores)):

    s = scores[i]

    flag = i

    for j in range(i,len(scores)):

        if(scores[flag] < scores[j]):

            flag = j

    temp = ''

    x = 0

    temp = names[i]

    names[i] = names[flag]

    names[flag] = temp

    x = scores[i]

    scores[i] = scores[flag]

    scores[flag] = x

print(scores)   

print(names)
