    print('{} is the only one for you...'.format(names[1]))
else:
    print('Momo... No one is for you ...')

L1-056 猜数字

语言：Python (python3)

import math


N = int(input())
s = 0
dic = {}
for i in range(N):
    guess = input().split()
    guess[1] = int(guess[1])
    s += guess[1]
    dic[guess[0]] = guess[1]
s //= N * 2
for key in dic.keys():
    dic[key] = math.fabs(s - dic[key])
print(s, sorted(dic.items(), key=lambda x: x[1])[0][0])

L1-059 敲笨钟

语言：Python (python3)

N = int(input())
for i in range(N):
    s = input().split(',')
    if s[0][-3:] == 'ong' and s[1][-4:-1] == 'ong':
        s[1] = s[1].replace(' '.join(s[1].split()[-3:]), 'qiao ben zhong.')
        print(','.join(s))
    else:
        print('Skipped')
