【问题描述】：

```
def run_loop(self):
    while True:
        event, values = self.read()
        if event == None:
            break
        
        if event == "_EDIT_":
            info = {}
            info['first_name'] = values['_FIRST_NAME_'] if len(values['_FIRST_NAME_'].strip()) > 0 else None
            info['last_name'] = values['_LAST_NAME_'] if len(values['_LAST_NAME_'].strip()) > 0 else None
            info['born'] = values['_BORN_'] if len(values['_BORN_'].strip()) > 0 else None
            info['moto'] = values['_MOTO_'] if len(values['_MOTO_'].strip()) > 0 else None
            if len(values['_PHOTO_']) != 0:
                with open(values['_PHOTO_'], 'rb') as f:
                    info['photo'] = f.read()
            elif self.has_photo == False:
                info['photo'] = None
            else:
                current_employee = employee.WorkerManager.current_employee()
                info['photo'] = current_employee.photo
            info['employee_id'] = employee.WorkerManager.current_id()
    
    self.close()
```

类员工：

def __init__(self, **employee_info):
    self.employee_id = employee_info['employee_id']
    self.first_name = employee_info['first_name']
    self.last_name = employee_info['last_name']
    self.born = employee_info['born']
    self.moto = employee_info['moto']
    self.photo = employee_info['photo']
    self.company_position = employee_info['company_position']

def __str__(self) -> str:
    worker_info = []
    if self.first_name is not None:
        worker_info.append(self.first_name)
    if self.last_name is not None:
        worker_info.append(self.last_name)

    return " ".join(worker_info)

错误名称： self.first_name = employee_info['first_name'] KeyError：'first_name'

多次检查mysql，正确的名称仍然显示错误 谢谢 在 前进
