import threading
def sayhello():
print "hello world"
global t #Notice: use global variable!
t = threading.Timer(5.0, sayhello)
t.start()
t = threading.Timer(5.0, sayhello)
t.start()
You can use the isAlive method on the thread to check if it is already running. 您可以在线程上使用isAlive方法来检查它是否已在运行。 On similar lines, if you were running a process instead, then you could write a pid file everytime you start the process and query the OS for the status of that specific pid anytime you required. 在类似的行上,如果您正在运行一个进程,那么每次启动进程时都可以编写一个pid文件,并在需要时随时向操作系统查询该特定pid的状态。
Check the following link for more on isAlive. 有关isAlive的更多信息,请查看以下链接。
