Get shell output from python script using QProcess

Question

I am writing a program with PyQT6 to update a progress bar based on output of the pagekite.py file, I'm using QProcess to call the script and a function to handle the output, but the output from the shell when i run the file looks like this:

>>> Hello! This is pagekite.py v1.5.2.201011.                   [CTRL+C = Stop]
    Connecting to front-end relay 00.00.000.00:000 ...
     - Relay supports 10 protocols on 23 public ports.
     - Raw TCP/IP (HTTP proxied) kites are available.
     - To enable more logging, add option: --logfile=/path/to/logfile
~<> Flying localhost:80 as https://test.pagekite.me/
 << pagekite.py [exiting]  Good-bye!

But when i get the output of the stdout of QProcess it look like this:

ts=63837a93; t=2022-11-27T14:56:19; ll=7; connect=000.000.00.000:000
