Python 报错：_io.TextIOWrapper' object is not callable

翻译为：io.TextIOWrapper 对象不可调用

elif info_list[2] == 'set' and info_list[3] == 'age':
     RESULT[info_list[1]]['age'] == info_list[-1]
     print("Update {} {} success!".format(info_list[1], info_list[3]))
     logTime = datetime.now().strftime("%Y-%m-%d %T")
     with open('log/action.log', 'a+') as ActionLog:
        ActionLog.write('{}: admin {} update user {} age {}\n.'.format(logTime,USERINFO[0], info_list[1], info_list[-1]))
        
fd = open('data/Table_date.file', 'w')
fd.write(json.dumps(RESULT))
fd.close()

原本是赋值的，我写多一个等号，变成判断了

== : 判断

= ：赋值

把 RESULT[info_list[1]]['age'] == info_list[-1] 改成 
RESULT[info_list[1]]['age'] = info_list[-1]
