Pythonint与byte类型相互转化
1根据Python⾃定义的功能，使⽤to_bytes函数转化int类型数据为byte型，然后使⽤from_bytes将byte类型数据转化为int型。

10 bytes.

12 The byteorder argument determines the byte order ud to reprent the
13 integer. If byteorder is 'big', the most significant byte is at the
14 beginning of the byte array. If byteorder is 'little', the most
15 significant byte is at the end of the byte array. To request the native

18 The signed keyword-only argument determines whether two's complement is
19 ud to reprent the integer. If signed is Fal and a negative integer
20 is given, an OverflowError is raid.

2data_byte = _bytes(4, byteorder='little', signed=True)
3print(type(data_byte), data_byte)
4data_int = int.from_bytes(data_byte, byteorder='little', signed=True)

输出结果：

<class 'int'> 100
