    Hope this will help

    records = []

if __name__ == '__main__':
    for _ in range(int(input())):
        name = input()
        score = float(input())
        records.append([name, score])
        
scores = sorted(list(set([i[1] for i in records])))
scores = scores[1]
a = []
for i in records :
    if i[1] == scores :
        a.append(i[0])
a1 = sorted(a)

for i in a1 :
    print(i)

    All test cases passed

    if name == 'main': students=[] student=[] for _ in range(int(input())): name = input() score = float(input()) students.append([name,score])

    score=sorted(set([student[1] for student in students]))
second_lowest=score[1]

names=([student[0] for student in students if second_lowest==student[1]])
names.sort()

    for i in names: print(i)
