Python线程池编程和参数的传递

#kwargs形式给线程传参
#因为没有args形式的参数，所以第一个为None
argslist = [(None, value1), (None,value2), (None,value3)]
#把每个线程当作一个请求，makesRequests将每个线程创建成一个请求
threadRequests = threadpool.makeRequests(eat,argslist)

#将线程池中的每个线程请求放到线程池中
for request in threadRequests:
thPool.putRequest(request)
#开启，启动线程池
#wait会等待所有的子线程执行完后再执行wait()后面的代码
thPool.wait()
