直接上代碼
import threading
import time
def run():
time.sleep(2)
print('當(dāng)前子線程的名字是： ', threading.current_thread().name)
time.sleep(2)
if __name__ == '__main__':
start_time = time.time()
print('這是主線程：', threading.current_thread().name)
thread_list = []
for i in range(5):
t = threading.Thread(target=run)
thread_list.append(t)
for t in thread_list:
t.start()
for t in thread_list:
t.join()
print('主線程結(jié)束了嚷那！' , threading.current_thread().name)
print('一共用時(shí)：', time.time()-start_time)
