Since Python 3.0, strings are stored as Unicode, i.e. each character in the string is represented by a code point. So, each string is just a sequence of Unicode code points. For efficient storage of these strings, the sequence of code points is converted into asetof bytes. The process ...
str(s, 'utf8')和s.decode('utf8')等价。 如果字符串在代码中被定义为s=u'中文',则s就是python内部编码unicode。 unicode类型再解码会报错。 判断一个字符串是否为unicode方法isinstance(s, unicode),python2中的unicode和python3中的str等价,所以在python3中判断一个字符串是否为unicode方法为isinstance(s, s...
section 步骤1: 将中文字符串转换成Unicode - 将中文字符串赋值给一个变量 section 步骤2: 将Unicode编码为UTF-8 - 使用encode函数对Unicode字符串进行UTF-8编码 类图 使用mermaid语法绘制类图,展示与中文转UTF-8编码相关的类和方法。 str+decode(encoding)+encode(encoding) 总结 在本文中,我们介绍了如何实现Python...
代码 encoding = 'utf-8' def num_c2a(chnum_str): ch_nums = {'一':1, '二':2, '三':3, '四':4, '五':5, '六':6, '七':7, '八':8, '九':9, '壹':1, '贰':2, '叁':3, '肆':4, '伍':5, '陆':6, '柒':7, '捌':8, '玖':9} ch_digits = {'十':10,...
UTF-8 is the default encoding in Python. When you call the encode method on a string without passing it another encoding, it assumes you mean UTF-8. This is the right thing to do, so that's what the code in this course does. ...

Python添加对Unicode的支持,以Unicode表示的字符串用u’ABC’来表示。 字符串’xxx’虽然是ASCII编码,但也可以看成是UTF-8编码,而u’xxx’则只能是Unicode编码。 把u’xxx’转换为UTF-8编码的’xxx’用encode(‘utf-8’)方法。 1>>> u'ABC'.encode('utf-8')2'ABC'3>>> u'中文'.encode('utf-8')...
在Python中,你可以使用open函数打开文件时指定编码方式为utf-8。这样,当你写入文件时,Python会自动将字符串转换为utf-8编码。 with open('file.txt', 'w', encoding='utf-8') as f: f.write(string) 使用错误处理参数:如果你不想改变文件的编码方式,你也可以在open函数中使用error处理参数来避免异常的抛出...
