谈到非阻塞计时器到多个非阻塞计时器

Question

我有这样的非阻塞计时器：

import time 
class Timer: 
     def __init__(self): 
     self.status = 0 
    def update(self, data, tv): 
     self.target = time.time() + data 
     self.status = 1 
    def set_status(self, state): 
     self.status = state 
    def get_status(self, tv): 
     return self.status 
    def get_left(self, tv): 
     return int(self.target-time.time()) 

，当我想例如在我的主循环定时器它的伟大工程为：

t = Timer() 
while 1: 
    #If timer is not active. 
    if t.get_status() == 0: 
     # Do some checks. 
     # Start timer with 60 seconds. 
     t.update(60) 
    #If timer is active. 
    if t.get_status() == 1: 
     print "%s seconds left." % str(t.get_left()) 
     if t.get_left() <= 0: 
      t.set_status(0) 
      # Timer is done do some stuff. 
time.sleep(1) 

我希望这能够处理多个定时器而不用线程。

这是我自己的解决方案，如果任何人有更好的主意，请让我知道。

import time 
class Timer: 
    def __init__(self): 
     self.status = {} 
     self.target = {} 
    def update(self, tv, data): 
     self.target[tv] = time.time() + data 
     self.status[tv] = 1 
    def set_status(self, tv, state): 
     self.status[tv] = state 
    def get_status(self, tv): 
     return self.status[tv] 
    def get_left(self, tv): 
     return int(self.target[tv]-time.time()) 

t = Timer() 
t.set_status('A', 0) 
t.set_status('B', 0) 
while 1: 
    # Timer A checks 
    if t.get_status('A') == 0: 
     print "Timer A checks." 
     # Start timer with 60 seconds. 
     t.update('A', 60) 
    if t.get_status('A') == 1: 
     print "A has %s seconds left." % str(t.get_left('A')) 
     if t.get_left('A') <= 0: 
      t.set_status('A', 0) 
      print "Timer A done." 
    # Timer B checks 
    if t.get_status('B') == 0: 
     print "Timer B checks." 
     # Start timer with 30 seconds 
     t.update('B', 30) 
    if t.get_status('B') == 1: 
     print "B has %s seconds left." % str(t.get_left('B')) 
     if t.get_left('B') <= 0: 
      t.set_status('B', 0) 
      print "Timer B done." 
    time.sleep(1)
