python2 编码与解码

 #!coding: utf-8
 s  = "特斯拉"
 s_to_unicode = s.decode("utf-8")
 unicode_to_gbk = s_to_unicode.encode("gbk")
 print s
 print ("unicode:", s_to_unicode)
 print ("gbk", unicode_to_gbk)

 gbk_to_unicode = unicode_to_gbk.decode("gbk")
 unicode_to_utf8 = gbk_to_unicode.encode("utf-8")
 print (gbk_to_unicode)
 print (unicode_to_utf8)

 输出结果
 [root@python]# python uncode.py
 特斯拉
 ('unicode:', u'\u7279\u65af\u62c9')
 ('gbk', '\xcc\xd8\xcb\xb9\xc0\xad')
