出错:
- >>> t1 = MyTimer()
- >>> t1
- 未开始计时!
- >>> t1.stop()
- 提示:请先调用start()开始计时!
- >>> t1.start()
- 计时开始...
- >>> t1.stop()
- Traceback (most recent call last):
- File "<pyshell#4>", line 1, in <module>
- t1.stop()
- File "D:\小甲鱼学习\时间.py", line 34, in stop
- self._calc()
- File "D:\小甲鱼学习\时间.py", line 41, in _calc
- self.lasted.append(self.end[index] - self.begin[index])
- TypeError: 'int' object is not subscriptable

帮帮忙
看错了,不是字符串,你定义的是整型,整型是不能索引的
