字节顺序可以是'big'(大端序)或'little'(小端序)。 以下是使用int.from_bytes()函数将字节数据转换为整数的示例代码: bytes_data=b'\x00\x01\x02\x03'integer_data=int.from_bytes(bytes_data,byteorder='big')print(integer_data)# 输出:66051 1. 2. 3. 4. 在上面的代码中,我们定义了一个字节数据b...
这可以通过使用int.from_bytes()函数来实现。该函数接受两个参数:bytes对象和字节序。字节序可以是'big'或'little',分别表示大端序和小端序。例如,你可以使用以下代码将bytes对象转换为整数: #将bytes对象转换为整数int_data=int.from_bytes(bytes_data,byteorder='big') 1. 2. 在上面的代码中,int.from_bytes...
| The bytes argument must be a bytes-like object (e.g. bytes or bytearray). | | The byteorder argument determines the byte order used to represent the | integer. If byteorder is 'big', the most significant byte is at the

In situations where larger integers are required, a 4-byte integer may be needed.Another important aspect to consider when using a 2-byte integer is the issue of endianness. Endianness refers to the order in which bytes of a multi-byte value are stored in memory. In a big-endi...
