在多個執行緒中執行
使用 threading.Thread
在另一個執行緒中執行一個函式。
import threading
import os
def process():
print("Pid is %s, thread id is %s" % (os.getpid(), threading.current_thread().name))
threads = [threading.Thread(target=process) for _ in range(4)]
for t in threads:
t.start()
for t in threads:
t.join()
# Out: Pid is 11240, thread id is Thread-1
# Out: Pid is 11240, thread id is Thread-2
# Out: Pid is 11240, thread id is Thread-3
# Out: Pid is 11240, thread id is Thread-4
