字节(Byte):计算机中数据的基本单位,通常包含8位(bit)。 整数(Integer):数学中的一个概念,表示没有小数部分的数。 字节序(Byte Order):字节在内存中的排列顺序,常见的有大端序(Big Endian)和小端序(Little Endian)。 Python中的字节处理 Python提供了多种处理字节的方法,其中bytes和
我们可以用mermaid语法来描述这两个过程之间的关系。 U32_INTintvalueBYTE_ARRAYbytesbyte_arrayconverts_toconverts_back_to 在这个关系图中,我们可以看到uint32与字节数组byte_array之间的相互转换关系。 实际应用场景 网络编程:在发送数据包时,通常需要将数值数据转换为字节,以便在网络上传输。 文件格式:比如 BMP、...
If it is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode(). 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 th...
The source parameter can be used to initialize the byte array in the following ways: TypeDescription String Converts the string to bytes using str.encode() Must also provide encoding and optionally errors Integer Creates an array of provided size, all initialized to null Object A read-only buff...

Now that we have covered how to convert the most common type of data, i.e. integers to ByteArrays, next let us address the 2nd most common datatype: “Strings”! Storing a String When working with strings we can use the following syntax to create the byte array from a string. ...
Return the integer represented by the given array of bytes. bytes Holds the array of bytes to convert. The argument must either support the buffer protocol or be an iterable object producing bytes. Bytes and bytearray are examples of built-in objects that support the ...
Next, we will use np.array() function to convert the list of floats to integer.int_list = np.array(float_list).astype(int).tolist() print(int_list) # [1, 3, 5]In the astype() function, we specified that we wanted it to be converted to integers, and then we chained the to...
