在输入的字符串中提取其中的姓名与职业信息，建立姓名职业字典并按键的顺序排列后输出，寻找其中职业字符串长度最长的条目（假设最长的只有一个）输出。 输入的字符串的格式形如（格式如下，逗号间隔，最后句号）： Kim is a bookkeeper, Kate is an actress, Bartholomew is a barber. 输出： [('Bartholomew', 'barber'), ('Kate', 'actress'), ('Kim', 'bookkeeper')] ('Kim', 'bookkeeper')
s = 'Kim is a bookkeeper, Kate is an actress, Bartholomew is a barber.'
List = []
lens = []
for i in s.split('.')[0].split(', '):
name = i.split(' ')[0]
occupation = i.split(' ')[3]
List.insert(0,(name,occupation))
lens.insert(0,len(occupation))
print(List)
print(List[lens.index(max(lens))])
