However, .decode() returns a string by decoding the bytes object using the UTF-8 encoding. The pair of bytes b'\xc3\xa9' represent the letter e with an acute accent, é. The .decode() method takes an optional a
Note: Strings do not have an associated binary encoding and bytes do not have an associated text encoding. To convert bytes to string, you can use thedecode()method on the bytes object. And to convert string to bytes, you can use theencode()method on the string. In either case, specify...
Files opened in binary mode (including 'b' in the mode argument) return contents as bytes objects without any decoding. In text mode (the default, or when 't' is included in the mode argument), the contents of the file are returned as str, the bytes having been first decoded using a...

Files opened in binary mode (appending 'b' to the mode argument) return contents as 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...
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
Python distinguishes between files opened in binary and text modes, even when the underlying operating system doesn't. Files opened in binary mode (appending 'b' to the mode argument) return contents as bytes objects without any decoding. In text mode (the default, or when 't' is appended ...
bytes 函数返回一个新的 bytes 对象,该对象是一个 0 <= x < 256 区间内的整数不可变序列。 9)Python3 None与数值做比较会报错,不同类型不能做比较,但是0和ture、false可以比较, Python2会做比较结果输出false 2 一行代码实现1-100之和 #for循环 ...
On the command line, you might be used to starting a program with a single string:Shell $ python timer.py 5 However, with run() you need to pass the command as a sequence, as shown in the run() example. Each item in the sequence represents a token which is used for a system ...
