UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa1 in position 311: invalid start byte

this is my script 

import subprocess
 
with open('IP-list.txt', 'rb') as f, open('ip_out.txt', 'wb') as f_out:
 
        for adress in f:
            adress = adress.strip()
            response = subprocess.run(['ping', adress], capture_output=True)
            print(response.stdout.decode())
            f_out.write(response.stdout)

Hey, @Skaallet,

 Do you have any string data in the dictionary? Then that can't be encoded or decoded.
