python - 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

目前，它运行第一个线程，然后在完成后开始下一个线程。

如何让所有线程同时启动？

我觉得有点愚蠢，但从未真正调用线程......

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
