假设我有以下四个功能:
def foo():
subprocess.Popen('start /B someprogramA.exe', shell=True)
def bar():
subprocess.Popen('start /B someprogramB.exe', shell=True)
def foo_kill():
subprocess.Popen('taskkill /IM someprogramA.exe')
def bar_kill():
subprocess.Popen('taskkill /IM someprogramB.exe')
如何交替运行 foo 和 bar 函数,例如 30 分钟?含义:第 1 次 30 分钟 - 跑步foo
,第 2 次 30 分钟 - 跑步bar
,第 3 次 30 分钟 - 跑步foo
,依此类推。每次新的运行都应该“杀死”前一个线程/函数。
我有一个倒数计时器线程,但不确定如何“交替”这些功能。
class Timer(threading.Thread):
def __init__(self, minutes):
self.runTime = minutes
threading.Thread.__init__(self)
class CountDownTimer(Timer):
def run(self):
counter = self.runTime
for sec in range(self.runTime):
#do something
time.sleep(60) #editted from 1800 to 60 - sleeps for a minute
counter -= 1
timeout=30
c=CountDownTimer(timeout)
c.start()
编辑:我对 Nicholas Knight 输入的解决方案......
import threading
import subprocess
import time
timeout=2 #alternate delay gap in minutes
def foo():
subprocess.Popen('start /B notepad.exe', shell=True)
def bar():
subprocess.Popen('start /B calc.exe', shell=True)
def foo_kill():
subprocess.Popen('taskkill /IM notepad.exe')
def bar_kill():
subprocess.Popen('taskkill /IM calc.exe')
class Alternator(threading.Thread):
def __init__(self, timeout):
self.delay_mins = timeout
self.functions = [(foo, foo_kill), (bar, bar_kill)]
threading.Thread.__init__(self)
def run(self):
while True:
for f, kf in self.functions:
f()
time.sleep(self.delay_mins*60)
kf()
a=Alternator(timeout)
a.start()
工作正常。
