# unicode string to be converted u_string = 'This is a test.' # encoding the unicode string to byte string b_string = codecs.encode(u_string, 'utf-8') print(b_string) 输出: b'This is a test.' 在这个例子中,我们有一个 统一码字符串 .我们使用该方法将此 Unicode 字符串转换为字节字...
如上运行结果,bytes转换为unicode为解码,uicode转为bytes数据类型为编码。 由上图所示,在不同的编码之间转换的时候,我们都要经过unicode这个中转站,没办法,虽然unicode老大哥强大呢,当我们想把utf-8编码的数据转换为gbk的,我们就需要把utf-8的数据先解码成unicode,再由unicode编码成gbk。 在py2和py3中有个重要的...
There appears to betwo different ways to convert a string to bytes, as seen in the answers to TypeError: 'str' does not support the buffer interface 从TypeError的答案中可以看出,有两种不同的方法可以将字符串转换为字节:'str'不支持缓冲区接口 Which of these methods would be better or more Pyt...

• Python bytestring: a series of bytes which represent a sequence of characters. It's default encoding is ASCII. This is the "normal", non-Unicode string in Python <3.0. • Python字节串:一连串代表字符串序列的字节集合.默认以ascii编码.在python3.0以下,这是一种常见的非unicode字符串. ...
Edit: 由于python会自动将字符串转换为Unicode,因此无法看到值,但可以创建一个函数来生成该值。 def get_string_unicode(string_to_convert): res = '' for letter in string_to_convert: res += '\\u' + (hex(ord(letter))[2:]).zfill(4) return res Result: >>> get_string_unicode('abc') '...
在用Python 2.7测试之后,需要在unquote()之前encode()使用str(纯文本)而不是unicode #-*- coding: utf-8 -*-import urlparse url = u'/wiki/Category:%e6%89%93%E7%A3%9A%E5%A1%8A'url = url.encode('utf-8') # convert `unicode` to `str`url = urlparse.unquote(url) # convert `%e6%89%...
for instance transfer it over the network, or save it to a disk file. To convert a string of bytes to a unicode string is known as decoding. Use unicode(’…’, encoding) or ‘…’.decode(encoding). You typically decode a string of bytes whenever you receive string data from the netw...
Python 3 introduced a sharp distinction between strings of human text and sequences of raw bytes. Implicit conversion of byte sequences to Unicode text is a thing of the past. This chapter deals with Unicode strings, binary sequences, and the encodings used to convert between them....
