Python built-in functions after 2.6

#10进制转为2进制
>>> Bin (10)
' 0b1010 '

#2进制转为10进制
>>> Int ("1001", 2)
9

#10进制转为16进制
>>> Hex (10)
' 0xa '

#16进制到10进制
>>> int (' FF ', 16)
255

>>> int (' 0xAB ', 16)
171

#十进制转为八进制
>>print ("%o"% 10)
>>12


#16进制到2进制
>>> Bin (0xa)
' 0b1010 '

#10进制到8进制
>>> Oct (8)
' 010 '

#2进制到16进制
>>> Hex (0b1001)
' 0x9 '

#IP地址之间的转换
Import socket
Import struct
def ip2hex (IP):
Return Hex (Struct.unpack ("! I ", Socket.inet_aton (IP)) [0])

def ip2long (IP):
Return Struct.unpack ("! I ", Socket.inet_aton (IP)) [0]

def long2ip (Lint):
Return Socket.inet_ntoa (Struct.pack ("! I ", lint))
