 我的代码(其实就是鱼老师上课讲的,我只是做了时间模块函数的替换)
 
 
 #计时器
 import time
 class Mytimer:
 def __init__(self):
 self.unit = ['年','月','日','时','分','秒']
 self.prompt = "未开始计时"
 self.begin = 0
 self.end = 0
 self.lasted = []
 
 
 def __str__(self):
 return self.prompt
 
 __repr__ = __str__
 
 def __add__(self,other):
 prompt = "总共运行了:"
 result = []
 for index in range(6):
 result.append(self.lasted[index] + other.lasted[index])
 if result[index]:
 prompt  +=(str(result[index])+self.unit[index])
 return prompt
 
 
 def start(self):
 self.begin = time.perf_counter()
 self.prompt = "提示:请先调用stop()停止计时"
 print("计时开始")
 
 def stop(self):
 
 if not self.begin:
 print("提示:请先调用start()开始计时")
 else:
 self.end = time.perf_counter()
 self.__calc()
 print("计时停止")
 def __calc(self):
 self.lasted = []
 self.prompt = "总共运行了:"
 for index in range(6):
 
 self.lasted.append(abs(self.end[index] - self.begin[index]))
 
 if self.lasted[index]:
 self.prompt += (str(self.lasted[index]+self.begin[index]))
 self.begin = 0
 self.end = 0
 
 
 
 
 
 
 
 
localtime()的结果是一个元组,perf_counter()的结果是一个浮点数,不能直接替换。 |
