import subprocess,time,psutil 
proc = subprocess.Popen("C:\\downloads\\b.bat",creationflags=subprocess.CREATE_NEW_CONSOLE) 
time.sleep(10) 

pobj = psutil.Process(proc.pid) 
# list children & kill them 
for c in pobj.children(recursive=True): 
    c.kill() 
pobj.kill() 

b.bat 内容
ping -t baidu.com

10秒后ping关闭窗口

2，cmd 运行python 脚本,并关闭创建的 cmd窗口

• test03.py 脚本

import subprocess,time,psutil 
command = "C:\\downloads\\b.bat"
proc = subprocess.Popen(command,creationflags=subprocess.CREATE_NEW_CONSOLE) 
time.sleep(5) 

pobj = psutil.Process(proc.pid) 
# list children & kill them 
for c in pobj.children(recursive=True): 
    c.kill() 
pobj.kill() 

• b.bat 脚本

python "C:\\win10\\test01.py"

• test01.py

import requests
from time import sleep
i = 0
while (i < 10):
    print (i)
    sleep(1)
    i = i + 1
    url = requests.get("http://www.baidu.com")
    status = url.status_code
    print (status)
