一、多個線程之間PID的區別

主進程跟線程的pid是一樣的

from threading import Thread
from multiprocessing import Process
import os

def task():
    print(‘%s is running‘ %os.getpid())

if __name__ == ‘__main__‘:
    t1=Thread(target=task,)
    t2=Thread(target=task,)
    t1.start()
    t2.start()
    print(‘主‘,os.getpid())

輸出：
6700 is running
6700 is running
主 6700

二、多個進程PID的區別

多個進程的PID完全不一樣

from threading import Thread
from multiprocessing import Process
import os

def task():
    print(‘%s is running‘ %os.getpid())

if __name__ == ‘__main__‘:
    t1=Process(target=task,)
    t2=Process(target=task,)
    t1.start()
    t2.start()
    print(‘主‘,os.getpid())



輸出：
主 2040
7104 is running
2768 is running
