Python capture subprocess output after termination

Question

I am trying to get subprocess output (on Windows) at the time the TimeoutExpired exception is raised. Any ideas?

try:
    proc = subprocess.run(cmd,timeout=3

Here is the way for capturing stdout for multiprocessing.Process

import app
import sys
import io
from multiprocessing import Process


def run_app(some_param):
    sys.stdout = io.TextIOWrapper(open(sys.stdout.fileno(), 'wb', 0), write_through=True)
    app.run()

app_process = Process(target=run_app, args=('some_param',))
app_process.start()
# Use app_process.termninate() for python <= 3.7.
app_process.kill()
