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...
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 argument to specify the encoding: text = data.decode("utf-8") print(...
Python中的encode负责将Unicode字符串转换为特定编码格式的字节流，而decode负责将字节流还原为Unicode字符串。以下是关于encode和decode的详细解释：encode方法： 功能：将Unicode字符串转换为特定编码格式的字节流。 参数：接受编码格式和错误处理策略作为参数。如果不指定编码，Python默认使用UTF8。 示例：s =...
响应头(使用浏览器开发者工具访问) 在之前的屏幕截图中看到的信息是在对www.python.org发出的请求期间捕获的。 在向服务器发出请求时,还可以提供所需的 HTTP 头部。通常可以使用 HTTP 头部信息来探索与请求 URL、请求方法、状态代码、请求头部、查询字符串参数、cookie、POST参数和服务器详细信息相关的信息。 通过HTT...
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. ...

Now that we have learned how to use the string constructor of the ByteArray class, next, let us have a look at how you can convert an object of the Bytes class into ByteArray class. Converting Bytes into ByteArray Let’s assume you are working with a read-only image and you wish to...
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...
