os.linesep. If newline is '' or '\n', no translation takes place. If newline is any of the other legal values, any '\n' characters written are translated to the given string.
bytes objects without any decoding. In text mode (the default, or when 't' is appended to the mode argument), the contents of the file are returned as strings, the bytes having been first decoded using a platform-dependent encoding or using the specified encoding if given. 'U' mode is ...
Since bytes objects are sequences of integers (akin to a tuple), for a bytes object b, b[0] will be an integer, while b[0:1] will be a bytes object of length 1. (This contrasts with text strings, where both indexing and slicing will produce a string of length 1)...
Passing theencodingargument tostrallows decoding anybytes-like objectdirectly, without needing to make a temporary bytes or bytearray object. Changed in version 3.1: Added support for keyword arguments. 其实编码解码的关系就是如下: 1 2 3 str->bytes:encode编码 bytes->str:decode解码 1 字符串通过编...

then you can convert unicode string to utf-8 byte string with: text = text.encode('UTF-8') And if source encoding is utf-8 you can just pass byte string from files.read() to your result string without senseless decode/encode steps (from utf-8 bytes to string and again to utf-8 ...

If you want to process the char* as text, decode it from data bytes to text appropriately. For example if the value represents a simple ASCII string: >>> s = b'ascii string' >>> print(s) b'ascii string' >>> print(s.decode('ascii')) ascii string .decode() takes a...

Strings can beencodedto bytes, and bytes can bedecodedback to strings. >>> '€20'.encode('utf-8') b'\xe2\x82\xac20' >>> b'\xe2\x82\xac20'.decode('utf-8') '€20' Think of it this way: a string is an abstract representation of text. A string consists of characters, which ...
