Thebytearrayfunction returns a mutable array of bytes. Unlikebytesobjects,bytearraycan be modified after creation. Key characteristics: mutable sequence of integers (0-255), supports common sequence operations, and can be converted to/from bytes and strings with specified encodings. Creating bytearray...
# 使用字节字符串初始化byte_array_string=b'hello'print(byte_array_string)# 输出:b'hello' 1. 2. 3. 方法3: 使用bytearray() bytearray是一个可变的byte类型数组,适合那些需要修改内容的场景。 # 初始化一个可变的byte数组byte_array_mutable=bytearray(5)print(byte_array_mutable)# 输出:bytearray(b'...
print(byte_array)# Output: bytearray(b'\x02\x03\x05\x07') bytearray() Syntax The syntax ofbytearray()method is: bytearray([source[, encoding[, errors]]]) bytearray()method returns a bytearray object (i.e. array of bytes) which is mutable (can be modified) sequence of integers ...
Python内置函数——bytearray()-暂疑 英文文档: classbytearray([source[,encoding[,errors]]]) Return a new array of bytes. Thebytearrayclass is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described inMutable Sequence ...
| Construct an mutable bytearray object from: | - an iterable yielding integers in range(256) | - a text string encoded using the specified encoding | - a bytes or a bytearray object | - any object implementing the buffer API.
1.2 mutable: 可变数据类型允许你在创建后修改其值。Python中的可变数据类型包括: list(列表) dict(字典) set(集合) bytearray(字节数组) 示例: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 if__name__=='__main__':列表=['北京','上海','深圳','广州']print(f'origin 列表 {列表} id(列表...
Mutable and Immutable Data Types in python explain using examples Now that we have learned what ByteArrays are and when to use them, let us go ahead and learn how to use the ByteArray data structure in our code! Initializing aByteArrayobject ...
bytearray objects contain single bytes – the former is immutable while the latter is a mutable sequence. Bytes objects can be constructed the constructor, bytes(), and from literals; use a b prefix with normal string syntax: b'python'. To construct byte arrays, use the bytearray() ...
