这道题最恶心的地方是相同成绩要按输入顺序输出,所以想到了用bisect模块。

bisect_left(a,num)返回num在有序序列a中的位置,如果num已经存在在a中,那就返回序列中num的位置

bisect_right(a,num)是如果num已经在a中,返回序列中最右边的num的右边位置

import bisect
while 1:
    try:
        n = int(input())
        sort = int(input())
        namelist = []
        score = []
        score2 = []
        name2 = []
        for i in range(n):
            name = input().split()
            namelist.append(name[0])
            score.append(int(name[1]))
        if sort:
            for i in range(n):
                place = bisect.bisect_right(score2, score[i])
                name2.insert(place,namelist[i])
                bisect.insort_right(score2, score[i])
            for i in range(n):
                print("%s %d"%(name2[i],score2[i]))
        else:
            for i in range(n):
                place = bisect.bisect_left(score2, score[i])
                name2.insert(place,namelist[i])
                bisect.insort_left(score2, score[i])
            for i in range(n-1,-1,-1):
                print("%s %d"%(name2[i],score2[i]))
    except:
        break
