Python-并行运行线程，而不是顺序运行

Question

代码：

from threading import Thread
import time

def main():
    print([threadID])
    time.sleep(5)
    pass

if __name__ == '__main__':
    threadID = 0
    while threadID < 5:
        main()
        threadID +=1

当前，它运行第一个线程，然后一旦完成，就开始下一个线程。

如何使所有线程同时启动？

Answer 1

我觉得有点愚蠢，但从未真正调用过线程...

代码：

from threading import Thread
import time

def main():
    print([threadID])
    time.sleep(5)
    pass

if __name__ == '__main__':
    threadID = 0
    while threadID < 5:
        t = Thread(target=main)
        t.start()
        threadID +=1
