python实现ping命令
假设我们有这么一项任务:简单测试局域网中的电脑是否连通.这些电脑的ip范围从192.168.0.101到192.168.0.200.??
import subprocess
cmd="cmd.exe"
begin=101
end=200
while begin<end:
??? p=subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,
?????????????????? stdin=subprocess.PIPE,
?????????????????? stderr=subprocess.PIPE)
??? p.stdin.write("ping 192.168.1."+str(begin)+"\n")
??? begin=begin+1
??? p.stdin.close()
??? p.wait()
??? print "execution result: %s"%p.stdout.read()
