Python实现获取命令行输出结果的方法

# coding: GB2312

importos, re

# execute command, and return the output

defexecCmd(cmd):

  r=os.popen(cmd)

  text=r.read()

  r.close()

  returntext

# write "data" to file-filename

defwriteFile(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))
