初始bytearray对象: bytearray(b'') 连续多次使用append函数添加字节后的bytearray对象: bytearray(b'Hello') 1. 2. 在这个示例中,我们连续多次使用append函数向bytearray对象添加字节,最终得到的结果是字母"H", “e”, “l”, “l”, "o"对应的ASCII码。 总结 通过本文的介绍,我们了解了append函数的定义、...
byte_array[1:4] # 获取第二到第四个字节的切片 1. 2. 字符编码与解码 bytearray可以通过decode方法将其内容解码为字符串,也可以使用encode方法将字符串编码为bytearray: byte_array.decode("utf-8") # 解码为字符串 text = "Python" byte_array = bytearray(text.encode("utf-8")) # 编码为bytearray...

converted to an array of bytes before writing; you can use thegetBytes()method for this purpose. We also need to passtrueas a second argument to its constructor. This second argument is for the Boolean append flag, and it’s done to indicate that we’re trying to append to an existing...

Python 通过内置类型bytearray存储二进制数据,相当于C语言中的char类型。 (1)应用场景: 二进制类型在一些基于内存数据块操作,比如串口通信,网络通信等。 (2)特性: bytearray每一个元素存储一个字节(0x00~0xff 或者 0 ~ 256)。 不同于字符串str,bytearray中的元素可以修改。
bytes (only for python3) 可以用于有些socket只接受byte类型的input ord ord() 函数是 chr() 函数(对于8位的ASCII字符串)或 unichr() 函数(对于Unicode对象)的配对函数 chr repr repr() 函数将对象转化为供解释器读取的形式。 和str()效果类似
