[Python] Controllo esistenza file semaforo

[clasku]

Usa sys.exit() invece di exit()

ciao!

ho provato anche con sys.exit:

import sys
import time
import shutil
from watchdog.events import FileSystemEventHandler
from watchdog.observers import Observer
from utils import get_first_file, count_csv

class MonitorFile(FileSystemEventHandler):

    def __init__(self):
        self.dir_semaforo = './test_semaforo'
        self.file_semaforo = './test_semaforo/semaforo'
        self.file_canc = './test_semaforo\semaforo'
        self.dir_to_move = './test_file/'
        self.dir_csv = './csv'
        self.observer = Observer()

    def crea_semaforo(self):
        if count_csv(self.dir_csv) > 0:
            file = get_first_file(self.dir_csv)

            shutil.move('./csv/' + file, self.dir_to_move + file)
            time.sleep(1)

            f = open(self.file_semaforo, "a")
            f.write("")
            f.close()
        else:
            sys.exit("ESCO")

    def run_observer(self):
        self.observer.schedule(self, path=self.dir_semaforo, recursive=False)
        self.observer.start()

        try:
            while (True):
                time.sleep(1)
        except (KeyboardInterrupt, SystemExit):
            self.observer.stop()
            time.sleep(1)

        self.observer.join()

    def on_deleted(self, event):
        if event.src_path == self.file_canc:
            if count_csv(self.dir_csv) > 0:
                self.crea_semaforo()
            else:
                self.observer.stop()
                print(count_csv(self.dir_csv)) # STAMPA ZERO -- CORRETTO
                print("DA USCIRE") # STAMPA IL PRINT -- CORRETTO
                sys.exit("ESCO") # NON STAMPA NULLA -- RIMASE APPESO

ti ho messo nei commenti il comportamente che ha.
in pratica il processo rimane appeso.
