[python] Popen defunct (zombie) process code fixed

import subprocess
import time

running_status = {
    "my_program": None
}

def run():
    running_status['my_program'] = subprocess.Popen(["python", "test.py"])


def kill_popen(process_name):
    # 좀비 프로세스를 제거하기 위해, popen 객체를 통해 return 값을 받습니다.
    s = running_status[process_name]
    s.terminate()
    time.sleep(0.5)
    s.poll()
    
run()
kill_popen('my_program')
