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、...
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。 bytearray中每一个元素的值为ASCII...

Here, n is the number of bytes to be read. First, let’s create a sample text file as shown below. Now let’s observe what each read method does: Example 1: my_file = open(“C:/Documents/Python/test.txt”, “r”) print(my_file.read(5)) ...

bytearray是Python中的一个内置数据类型,它类似于bytes对象,但具有可变性。这意味着可以在不创建新对象的情况下就地修改bytearray的内容。它通常用于存储和处理二进制数据,例如图像、音频和网络数据。 2. 创建bytearray 从字符串创建 可以使用encode方法将字符串转换为bytearray对象: ...
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
