python内建模块之struct

1.Python提供了一个struct模块来解决bytes和其他二进制数据类型的转换。

struct的pack函数把任意数据类型变成bytes：

import struct
print(struct.pack('>I',10240099))

运行结果：

"C:\Program Files\Python36\python.exe" C:/Users/Administrator/PycharmProjects/Python全网练习/常用内置模块.py
b'\x00\x9c@c'

Process finished with exit code 0

2.unpack把bytes变成相应的数据类型：

import struct
print(struct.unpack('>I',b'\x00\x9c@c'))

运行结果：

"C:\Program Files\Python36\python.exe" C:/Users/Administrator/PycharmProjects/Python全网练习/常用内置模块.py
(10240099,)

Process finished with exit code 0
