[Tutor] need help writing subprocess output to file(s)

[Matthew Herzog]

Hi all.
I have to run a utility (sdptool) that checks the firmware versions on >500
servers.
What I pasted below works but the stdout needs to be written to a file, one
per IP address.
How do I capture the stdout to files? Even a single logfile would work.
Thanks.

#!/usr/bin/python3
import subprocess

with open("ips.txt") as ip_list:
    ips = ip_list.readlines()

for ip in ips:
    output = subprocess.Popen(["/opt/bin/sdptool", ip, "check"])
