针对iconv()函数，我就试着写了个utf-8和gbk的url编码转换

import os,urllibprint"""if u want change gbk to utf-8,please input gbk,so as input utf-8.input exit and exit,others make u try agin"""st = raw_input()def utf8cwgbk(st):    if st=="utf-8":        print "input string"        url1 = raw_input()        st1 = urllib.unquote(url1)        st2 = st1.decode("utf-8").encode("gbk")        url2 = urllib.quote(st2)        print """utf-8的url编码---gbk的url编码---utf-8的汉字---gbk的汉字"""        print url1,'---',url2,'---',st1,'---',st2        os.system('pause')    if st=="gbk":        print "input string"        url1 = raw_input()        st1 = urllib.unquote(url1)        st2 = st1.decode("gbk").encode("utf-8")        url2 = urllib.quote(st2)        print """utf-8的url编码---gbk的url编码---utf-8的汉字---gbk的汉字"""        print url1,'---',url2,'---',st2,'---',st1        os.system('pause')    if st=="exit":        os.system('exit')    else:        print"""please try again.if u want change gbk to utf-8,please input gbk,else input utf8,finally input exit"""        st = raw_input()        utf8cwgbk(st)if __name__=="__main__":    utf8cwgbk(st)
