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)
