Python struct Module
Example
Pack integers into bytes and unpack them:
import struct
packed = struct.pack('ii', 42, 100)
print(f'Packed bytes: {packed}')
unpacked = struct.unpack('ii', packed)
print(f'Unpacked values: {unpacked}')

Definition and Usage
The struct module converts between Python values and C structs represented as Python bytes objects.
Use it to work with binary data from files or networks, or to interface with C libraries that use packed binary data.
