You can use two signals to kill a running subprocess call i.e., signal.SIGTERM and signal.SIGKILL; for example

process = subprocess.Popen(..)
..
# killing all processes in the group
os.killpg(process.pid, signal.SIGTERM)
time.sleep(2)
if process.poll() is None:  # Force kill if process is still alive
    time.sleep(3)
    os.killpg(process.pid, signal.SIGKILL)
