Check files modification from a process with Python watchdog

I’m trying to use Python watchdog and I don’t know if it’s possible to check if a process modified/created/deleted files, can anyone help me?

import sys
import time
import logging
from watchdog.observers import Observer
from watchdog.events import LoggingEventHandler


logging.basicConfig(level=logging.INFO, format=' %(message)s')
path = sys.argv[1] if len(sys.argv) > 1 else '.'

event_handler = LoggingEventHandler()

observer = Observer()
observer.schedule(event_handler, path, recursive=True)

observer.start()
try:
    while True:
        time.sleep(1)
except KeyboardInterrupt:
    observer.stop()
observer.join()

How can I change the code to show the process that changed files in a specific folder?
