字符编码 encode、decode

# 字符串的编码方式

str = '你好，世界'
str_unicode_to_gbk = str.encode('gbk')
str_unicode_to_utf8 = str.encode('utf-8')
str_unicode_to_gb2312 = str.encode('gb2312')
str_unicode_to_gbk_to_unicode_to_gb2312 = str.encode('gbk').decode('gbk').encode('gb2312')
str_unicode_to_gbk_to_unicode_to_utf8 = str.encode('gbk').decode('gbk').encode('utf-8')
print('gbk; ', str_unicode_to_gbk)
print('utf-8; ', str_unicode_to_utf8)
print('gb2312; ', str_unicode_to_gb2312)
print('gb2312; ', str_unicode_to_gbk_to_unicode_to_gb2312)
