python 多线程执行函数,以及调用函数时传参
import threading def func1(): print(‘this is function1‘) def func2(x,y): print(‘this is function2‘) print(x+y) threads = [] threads.append(threading.Thread(target=func1)) threads.append(threading.Thread(target=func2,args=(11,22,))) print(threads) if __name__ == ‘__main__‘: for t in threads: print(t) t.start()
python 多线程执行cmd终端命令(os.system),
# import threading # import time # class ThreadImpl(threading.Thread): # def __init__(self, num,cmds): # threading.Thread.__init__(self) # self._num = num # self._cmds = cmds # # def run(self): # global total, mutex # # # 打印线程名 # # print(threading.currentThread().getName()) # os.system(self._cmds) # for x in range(0, int(self._num)): # # 取得锁 # mutex.acquire() # # total = total + 1 # # 释放锁 # mutex.release() # # # if __name__ == ‘__main__‘: # starttime = time.time() # global mutex # mutex = threading.Lock() # threads = [] # for x in range(len(cmdList)): # threads.append(ThreadImpl(100,cmdList[x])) # # 启动线程 # for t in threads: # t.start() # # 等待子线程结束 # for t in threads: # t.join() # # totaltime = time.time() - starttime # # print(‘========‘) # # print(totaltime)
