#!/usr/bin/env python3 str = '宇久科技' # encoding可以省略 str_utf8 = str.encode(encoding="utf-8") str_gbk = str.encode("GBK") print ("str:",str) print ("utf8:",str_utf8) print ("gbk:",str_gbk) print ('*'*80) dstr_utf8 = str_utf8.decode("UTF-8") dstr_gbk = str_gbk.decode(encoding="GBK") print ("utf8解码:",dstr_utf8) print ("gbk解码:",dstr_gbk) |
二、运行结果
