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...
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 = bytearray(receive_data()) # 处理接收的数据 数据解析 bytearray还用于解析二进制数据,如处理二进制文件格式、解析传感器数据等。 sensor_da...
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。 复制 with open("image.jpg", "rb") as file: image_data = bytearray(file.read()) # 可以在bytearray中修改图像数据 1. 2. 3. 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。
bytearray()takes three optional parameters: source (Optional)- source to initialize the array of bytes. encoding (Optional)- if the source is astring, the encoding of the string. errors (Optional)- if the source is a string, the action to take when the encoding conversion fails (Read more...

先考虑的接收串口数据,那么格式是bytearray,下面需要处理成string格式来显示: 1 2 3 4 5 6 7 8 #按string来显示,byarray代表接收到的数据 readstr=byarray.decode('utf-8')#这样就直接转换成str格式 #强制转换 readstr=str(byarray)#用这种方式得到的数据会带有b''字符 ...
