报错信息

[root@chenbj ~]# python ip.py 192.168.1.1
  File "ip.py", line 4
SyntaxError: Non-ASCII character '\xe6' in file ip.py on line 4, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
翻译:
SyntaxError：第4行文件ip.py中的非ASCII字符“\ xe6”，但未声明编码; 有关详细信息，请参阅http://www.python.org/peps/pep-0263.html

所以我们就要指定字符编码:养成良好习惯很重要.

[root@chenbj ~]# cat ip.py
#!/usr/bin/env python
# _*_ coding:utf-8 _*_                    

_*_ coding:utf-8 _*_ 是用来指定文件编码为utf-8的
