今天我们开始来总结一下python的内置函数,问我为什么写,是渐渐觉得很多东西可以直接调用,不需要引入package,那给我的感觉是:内置的应该是要掌握的基础,会有很强大的功能建立在你掌握了基础之上。 主题:今天涉及的主要是计算机编码转换涉及的函数,跳着来是为了把能比较的放一起 优势: 每一个function 除了解释, 例子,...

将'bytes'对象转换为字符串可以使用Python的decode()方法。decode()方法是将字节对象解码为字符串的方法。它接受一个参数,即编码类型,用于指定字节对象的编码方式。 以下是一个示例代码: 代码语言:python 代码运行次数:0 复制Cloud Studio 代码运行 # 定义一个字节对象 bytes_obj = b'Hello World' # 将字节对象...
When converting text to bytes, if a character is not defined in the target encoding, UnicodeEncodeError will be raised, unless special handling is provided by passing an errors argument to the encoding method or function. The behavior of the error handlers is shown in Example 4-6. Example 4-...
