小列表里寫的是同學的名字和成績？

scoreList = [

['a',98],

['c',45],

['b',70],

['d',85],

['h',85],

['f',92],

['g',30],

['e',65]

];

arrLen = len(scoreList);

for i in range(arrLen):

a = scoreList[i]

for j in range(arrLen):

b = scoreList[j-1]

if b[1]<a[1]:

scoreList[i],scoreList[j-1] = scoreList[j-1],scoreList[i]

print(scoreList)
