Send a signal/event to an independent process

So I have a completely independent process, with a known PID.

I want to send it some kind of interrupt from another unrelated process that will cause it to 'gracefully' exit.

In linux it would look something like this :

first_script:

def signal_handler(signum, stack):
    print("SIGNAL RECIEVED")
    sys.exit()

signal.signal(signal.SIGUSR1, handle_signal)
while True:
    print("Im working")

Second script:

known_pid = input("Enter pid")
os.kill(int(known_pid), signal.SIGUSR1)

Since, Windows doesn't support signaling in this way, it obviously won't work but I couldn't find any other simple solution (After quite extensive research).
