Python字符串的編碼和解碼

liwenqiu

先舉個(gè)例子：
#coding: gbk

unicodestring = u"Hello, 中國"

#Convent Unicode to plain Python string: "encode"
utf8string = unicodestring.encode("utf-8")
utf16string = unicodestring.encode("utf-16")
gbkstring = unicodestring.encode("gbk")
cp932string = unicodestring.encode("cp932")

#Convent plain Python string to Unicode: "decode"
unicodestring1 = unicode(utf8string, "utf-8")
unicodestring2 = unicode(utf16string, "utf-16")
unicodestring3 = unicode(gbkstring, "gbk")
unicodestring4 = unicode(cp932string, "cp932")

概括的說，調(diào)用一個(gè)unicode對(duì)象的encode方法，返回相應(yīng)編碼的string對(duì)象；調(diào)用某種編碼的string對(duì)象的decode或調(diào)用unicode方法，返回一個(gè)unicode對(duì)象
