Python struct pack mirroring

Below is example of my code:

import struct

data = []
for i in range(5):
    firmware_addr = 128*i
    p = struct.pack('>I', firmware_addr)
    print("Addr: {0}, pack: {1}".format(firmware_addr, p))

Output:

Addr: 0, pack: b'\x00\x00\x00\x00'
Addr: 128, pack: b'\x00\x00\x00\x80'
Addr: 256, pack: b'\x00\x00\x01\x00'
Addr: 384, pack: b'\x00\x00\x01\x80'
Addr: 512, pack: b'\x00\x00\x02\x00'

It is working fine. But I need to have output like this:

Addr: 0, pack: b'\x00\x00\x00\x00'
Addr: 128, pack: b'\x80\x00\x00\x00'
Addr: 256, pack: b'\x00\x01\x00\x00'
Addr: 384, pack: b'\x80\x01\x00\x00'
Addr: 512, pack: b'\x00\x02\x00\x00'

How can I do it?

Solution

  • Ok it was easier than i thought. Solution: p[::-1]
