我们可通过open函数打开文件,使用read方法读取文件内容,并使用bytes()构造函数将字符串转换为字节数组。下面是这个操作的示例流程图和对应代码: 打开文件读取内容转换为字节数组 下面是Python代码示例: # 文件读取并转换为字节数组deffile_to_byte_array(file_path):withopen(file_path,'rb')asfile:content=file.read...
bytearray在文件读写和处理二进制文件时非常有用,例如图像处理、音频处理和压缩文件操作。 with open("image.jpg", "rb") as file: image_data = bytearray(file.read()) # 可以在bytearray中修改图像数据 网络通信 在网络通信中,bytearray用于处理网络数据包,构建自定义协议和解析数据。 data_received = byte...

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 in the range 0 <= x < 256, which are used as the initial contents of the array. Without ...

二.str、bytes和bytearray区别 1.str是字符数据(如:文本,给人看的),bytes和bytearray是字节数据(如:二进制数据,给计算机看的),它们都是序列,可以进行迭代遍历。 2.str和bytes是不可变序列,通过str类型的通用函数,比如find()、replace()、islower()等函数修改后实际上是重新创建了新对象;bytearray是可变序列,可...
Let’s assume you are working with a read-only image and you wish to modify it, then first you need to make an editable copy. Situations like this are where our next constructor comes in. As mentioned previously, the Bytes class is just animmutableversion of the ByteArray class, i.e....
