魔法方法
不知道为啥运算t1+t2时总是出现typeerror的提醒，有哪位大神知道的，可以告诉我嘛，十分感谢import time as t
class MyTimer():
def __init__(self):
self.unit = ['年','月','天','时','分','秒']
self.prompt = "未开始计时!"
self.lasted = []
self.begin = 0
self.end = 0
def __str__(self):
return self.prompt
__repr__ = __str__
def __add__(self,other):
prompt = "总共运行了"
result = []
for index in range:
result.append(self.lasted+other.lasted)
if result:
prompt += (str(result) + self.unit)
return prompt
#开始计时
def start(self):
self.begin = t.localtime()
self.prompt = "提示：请先调用stop()停止计时!"
print("计时开始...")
#停止计时
def stop(self):
if not self.begin:
print("提示：请先调用start()开始计时！")
else:
self.end = t.localtime()
self._calc()
print("计时结束...")
#内部方法，计算运行时间
def _calc(self):
self.lasted = []
self.prompt = "总共运行了"
for index in range(6):
self.lasted.append(self.end - self.begin)
if self.lasted:
self.prompt += (str(self.lasted) + self.unit)
#为下一轮计时初始化变量
self.begin = 0
self.end = 0

总共运行了3秒

for index in range:
TypeError: 'type' object is not subscriptable type就是类型错误，
你看一下22行，str类型应该是int类型吧
