代码：

info = {}
with open('/home/bista/Desktop/data.txt') as input_file:
  for line in input_file:
    month,year, emp_id, bill_amount = (item.strip() for item in line.split('-', 4))
    month = dict(zip(('month','month'),map(str, month.split('/'))))
    info[id] = dict(zip(('month','emp_id','bill_amount'),(month,emp_id, bill_amount)))
    # print(info)
    create_new_dict = {}
    for id, record in info.items():
        # print(record)
        if record['month']['month'] == 'Jun':
          new= {record['emp_id']:{'emp_id':record['emp_id'],'bill_amount':record['bill_amount']}}
          # print(new)
          create_new_dict.update(new)
          # print("s",create_new_dict)
          max = 0.0
          for key,value in create_new_dict.items():
            # print(max)
            if float(value['bill_amount']) > max:
              max =float(value['bill_amount'])
              # print("emp_id:",value['emp_id'])
          print("emp_id:",value['emp_id'])

问题：

打印结果：

root@bista:/home/bista/Desktop# python3 get.py 
emp_id: 124
emp_id: 110
emp_id: 120
emp_id: 124

但结果应为emp_id：124
