Python 技术篇-通过管道命令获取cmd执行的结果，获取os.system()、subprocess.Popen()执行命令返回的结果

# -*- coding: UTF8 -*-
import os
 
cmd = os.popen('netstat -nao | findstr "%s"' % str("5003"))
print("读取cmd执行的结果为:\n" + cmd.read())

# -*- coding: UTF8 -*-
import subprocess

cmd_order = 'netstat -nao | findstr "%s"' % str("5003")
cmd_p = subprocess.Popen(cmd_order, shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
cmd_result = ""
for i in cmd_p.stdout.readlines():
    cmd_result += i.decode();
print("读取cmd执行的结果为:\n\n" + cmd_result)
