In Python, a bytearray is a mutable sequence of bytes. It can be used to store and manipulate binary data, such as images or sound files. However, sometimes you may need to convert a bytearray to a single byte. This article will discuss how to achieve this in Python. Converting Bytea...
bytes 和 bytearray 转换 bytearray 转 bytes 当需要将可变的bytearray转换为不可变的bytes时,可以直接使用bytes()构造函数。 #从 bytearray 转换为 bytesba=bytearray(b'Hello')b=bytes(ba)print(b)# 输出: b'Hello' 1. 2. 3. 4. bytes 转 bytearray 将bytes转换成bytearray也非常简单,只需使用bytearr...
