Question

您好我是python的新手，想要在循环中创建多个线程（如C风格）

for (;i < 10; i++)
 thread[i]= pthread_create(&thread[i],&attr,func)

我不知道如何在python中做同样的事情？基本上我想要那个thread []变量作为全局将立即创建所有线程然后将一次启动。我已经编写了一个类似的python程序，但我认为在上面的样式中使用它会更好。

def thread_create(thread_number):
    command_string = "Thread-" + "%d" %thread_number
    thread = myThread(thread_number, command_string)
    thread.start()

# Start new Threads

for i in range(5):
    thread_create(i)

Answer 1

您认为这更好吗？

for i in range(5):
    command_string = "Thread-" + "%d" % i
    thread = Thread(i, command_string)
    thread.start()

Answer 2

如果你想要一对一的等价物，那么可能就是这样：

threads = []
for i in xrange(10):
    t = Thread(target=aFunc, name="Thread-%d" % i)
    t.start()
    threads.append(t)

或者，如果你只是想建立线程对象，并在以后随意启动它们......

threads = []
for i in xrange(10):
    t = Thread(target=aFunc, name="Thread-%d" % i)
    threads.append(t)

threads[2].start()

Answer 3

重新使用你的thread_create函数和列表理解来获得你想要的东西。

def thread_create(thread_number):
    command_string = "Thread-" + "%d" %thread_number
    return myThread(thread_number, command_string)
    # start them later


# see note below
threads = [thread_create(x) for x in range(5)]

for t in threads:
    t.start()

注意：

threads = [thread_create(x) for x in range(5)]

只是
的简写
threads = [] for x in range(5): threads.append(thread_create(x))
