一、使用方法和执行效果请看图:
二、python实现代码:
复制代码 代码如下:
[root@yang python]# vi check_ip.py
#!/usr/bin/python
import os,sys
def check_ip(ipaddr):
import sys
addr=ipaddr.strip().split('.') #切割IP地址为一个列表
#print addr
if len(addr) != 4: #切割后列表必须有4个参数
print "check ip address failed!"
sys.exit()
for i in range(4):
try:
addr[i]=int(addr[i]) #每个参数必须为数字,否则校验失败
except:
print "check ip address failed!"
sys.exit()
if addr[i]=0: #每个参数值必须在0-255之间
pass
else:
print "check ip address failed!"
sys.exit()
i+=1
else:
print "check ip address success!"
if len(sys.argv)!=2: #传参加本身长度必须为2
print "Example: %s 10.0.0.1 "%sys.argv[0]
sys.exit()
else:
check_ip(sys.argv[1]) #满足条件调用校验IP函数
