threading daemon和non-daemon代码笔记

看python主线程是如何等待

import time
import threading

def foo(n):
    for i in range(n):
        print(i)
        time.sleep(1)

t1 = threading.Thread(target=foo, args=(10, ), daemon=True) # 尝试替换这里的10和下面20的顺序
t1.start()
t2 = threading.Thread(target=foo, args=(20, ), daemon=False)
t2.start()

time.sleep(2)
print(‘Main Thread Exiting‘)
