I want to get the information of a torrent file in a desired format through python

Question

I am writing code to parse tracker information in torrent file using python.

import bencoder
import sys

target = './'+sys.argv[1]

with open(target, 'rb') as torrent_file:
    torrent = bencoder.decode(torrent_file.read())

i=0
while True:
    try:
        print(torrent[b'announce-list'][i])
        i+=1
    except:
        break
    

The output is as follows.

[b'udp://tracker.openbittorrent.com:80/announce']

[b'udp://tracker.opentrackr.org:1337/announce']

I want to parse the value in the form below.

["tracker.openbittorrent.com", 80]

["tracker.opentrackr.org", 1337]

How should I parse it?
