 #IO操作

 import time;

 fileObj = open('log.txt','a');

 while(True):
     data = input('请输入要写入的内容 : ');

     if data == 'Q' or data == 'q':
         break

     curTime = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime());
     fileObj.write(curTime+ ' : ' + data+ '\n');

 fileObj.close();
 print('bye');
