使用read()方法可以将文件的内容读取到一个bytearray对象中。 步骤三:处理数据 一旦数据被读取到bytearray中,我们就可以进行分析或其他操作。 示例代码 以下是一个完整的示例代码,演示如何将RAW文件读取到bytearray: defread_raw_file_to_bytearray(file_path):try:withopen(file_path,'rb')asfile:data=bytearray...
If it is an integer, the array will have that size and will be initialized with null bytes. If it is an object conforming to the buffer interface, a read-only buffer of the object will be used to initialize the bytes array. If it is an iterable, it must be an iterable of integers...
If it is an object conforming to thebufferinterface, a read-only buffer of the object will be used to initialize the bytes array. If it is aniterable, it must be an iterable of integers in the range0<=x<256, which are used as the initial contents of the array. Without an argument,...

If the above answer feels insufficient do not worry as this section was meant to be a quick reference for those who are already familiar with the topic. Read on for a more complete answer where we have explained everything you need to know about ByteArrays with the help of examples!
首先要知道,Python内置了两种基本的二进制序列类型:Python3引入的不可变bytes类型和Python2.6添加的了可变bytearray类型。bytes或bytearray对象的各个元素是介于0-255之间的整数,而不像Python2的str对象那样是单个的字符。然而,二进制序列的切片始终是同一类型的二进制序列,包括长度为1的切片。 cafe = bytes('cafの',...
py 的字符串模型,也就是说py里怎样组织和划分的字符串问题,比如py3里的模型是 str(统一Unicode),bytes(字节串,以字节为单位的字节序列),bytearray。而py2里的字符串模型是 str(包括ASCII字符串和字节串),unicode字符串。 py2里把字符串和字节串混合,用一个str类型表示,是有些不对的。因为字符串是字符类型,...

str、byte、bytearray 只包含可打包对象的集合,包括 tuple、list、set 和 dict 定义在模块顶层的函数(使用def定义,[lambda]()函数则不可以) 定义在模块顶层的内置函数 定义在模块顶层的类 某些类实例,这些类的dict属性值或 [__getstate__()]()函数的返回值可以被打包(详情参阅打包类实例这一段) ...
