我有一个计时器，返回(至少我希望它(一些值。我有一个函数，外部计时器类，它应该查看计时器的返回值，如果该函数接收特定数据 - 仅在该特定时刻执行其他操作。
from time import time, sleep
class Clock:
def __init__(self):
self.oneSec = 0
self.secsPassed = 0 #counts all seconds that already passed, up to 59; then resets and counts again
self.minute = 0
self.hour = 0 #currently unused
self.day = 0 #currently unused
self.start_time = 0
self.start()
def start(self):
while self.secsPassed < 10:
self.start_time = time()
sleep(1)
self.oneSec = int(time() - self.start_time) #easiest way to measure a second
self.secsPassed += self.oneSec
print(f"{self.minute} minutes, {self.secsPassed} seconds")
self.getStats() #returns values without breaking the loop, at least I hope it does
if self.secsPassed == 10: #normally it'd be 59, but I wanted to do it quicker for sake of tests
self.secsPassed = -1 #with 0 after 1:59 minute there would be immediately 2:01
self.minute += 1
if self.minute == 2 and self.secsPassed == 0: #just to end test if everything works fine
break #for some reason it doesn't totally exit whole code, only stops counting, but I still have to manually exit the code from running
def getStats(self):
return self.day, self.hour, self.minute, self.secsPassed
现在我需要在 Clock 类之外的一个函数，它可以观察我的 Clock 的返回语句如何变化并相应地对它们做出反应。我已经做了一些编码，但它不起作用，我可能知道为什么，但我无法在 3 小时内想出解决方案。这是我当前的代码：
def clockChecker(clock):
while True: #I thought it'd be a good idea to loop since it has to be "conscious" the whole time to react on new returns, but... I guess this cannot work, after a few hours I realized that by running this function it gets the returned statement only once, so it can't update
if clock == (0, 0, 0, 3): #if clocks makes 3rd second
print("It works!")
break
我尝试使用线程、管道和池，但如果我的时钟检查器无效，则无济于事。 首先，我绝对需要有关我的时钟检查器的帮助，其次，我希望至少选择我应该使用哪一个(线程，管道，池(，因此它工作非常顺利。
你的方法会有一些困难。
第一个只是clockChecker功能，我相信你错过了一个.getStats()调用来做这项工作，它没有成功的机会。
即使进行了此更改(应该有效(，完全匹配也是非常危险的，并且会受到"在正确的时间不匹配"和"可能永远不会匹配"的影响。
处理此问题的一种方法是使用匹配超过特定时刻的>=或其他条件。 其他包括：threading.Event;将条件推入计时器的钩子;按原样执行逻辑，休眠三秒钟;协程以及更多:)
打印格式被修改，因为我使用 python 3.5
from time import time, sleep
import threading
class Clock:
def __init__(self):
self.oneSec = 0
self.secsPassed = 0 #counts all seconds that already passed, up to 59; then resets and counts again
self.minute = 0
self.hour = 0 #currently unused
self.day = 0 #currently unused
self.start_time = 0
#self.start()
def start(self):
while self.secsPassed < 10:
self.start_time = time()
sleep(1)
self.oneSec = int(time() - self.start_time) #easiest way to measure a second
self.secsPassed += self.oneSec
print("%d minutes, %d seconds"%(self.minute,self.secsPassed,))
# self.getStats() #returns values without breaking the loop, at least I hope it does
if self.secsPassed == 10: #normally it'd be 59, but I wanted to do it quicker for sake of tests
self.secsPassed = -1 #with 0 after 1:59 minute there would be immediately 2:01
self.minute += 1
if self.minute == 2 and self.secsPassed == 0: #just to end test if everything works fine
break #for some reason it doesn't totally exit whole code, only stops counting, but I still have to manually exit the code from running
def getStats(self):
return self.day, self.hour, self.minute, self.secsPassed
def clockChecker(clock):
while True: #I thought it'd be a good idea to loop since it has to be "conscious" the whole time to react on new returns, but... I guess this cannot work, after a few hours I realized that by running this function it gets the returned statement only once, so it can't update
if clock.getStats() == (0, 0, 0, 3): #if clocks makes 3rd second
print("It works!")
break
sleep(1)
clock=Clock()
th1=threading.Thread(target=lambda: clock.start())
th1.start()
th2=threading.Thread(target=clockChecker,args=(clock,))
th2.start()
th2.join()
th1.join()
如果您不介意改用另一条路线
def outside_func():
do something
return
class clock():
def __init__(self, arguments):
self.secspassed
def timer():
while True:
self.secspasswd += 1
if self.secspasswd % 3 == 0:
outside_func()
time.sleep(1)
我认为使用 +1 秒来设置时间值会减少偏见的增加。 编程+1需要一些时间，设置属性值也需要一些时间。当您+1时，实时时间已超过1秒，
