１，ip地址類(lèi)型轉(zhuǎn)換
??? import struct
??? import socket
??? struct.unpack('!I', socket.inet_aton('192.168.102.0'))
??? socket.inet_ntoa(struct.pack('!I', 3232261632))
２，默認(rèn)版本為python3的系統(tǒng)上臨時(shí)切換回python2
?? ln -s /usr/bin/python2 ./python
?? export PATH=$PWD:$PATH
?? 接下來(lái)執(zhí)行的python腳本將是python2
