Python实现获取命令行输出结果的方法

# coding: GB2312import os, re# execute command, and return the outputdef execCmd(cmd):  r = os.popen(cmd)  text = r.read()  r.close()  return text# write "data" to file-filenamedef writeFile(filename, data):  f = open(filename, "w")  f.write(data)  f.close()# 获取计算机MAC地址和IP地址if __name__ == '__main__':  cmd = "ipconfig /all"  result = execCmd(cmd)  pat1 = "Physical Address[/. ]+: ([/w-]+)"  pat2 = "IP Address[/. ]+: ([/./d]+)"  MAC = re.findall(pat1, result)[0]    # 找到MAC  IP = re.findall(pat2, result)[0]    # 找到IP  print("MAC=%s, IP=%s" %(MAC, IP))
