Problem while deleting a file

Question

I made a small log manager. It’s for something simple, so how is it fit. every day I want to delete and generate a new one, but my code is showing the following error:

The file is already being used by another process: 'test.log'

def manage_log():
    try:
        logging.basicConfig(filename=f"teste.log", level=logging.INFO)

        arquivo = open("teste.log")
        arq = arquivo.read()
        arquivo.close()

        dia = str(datetime.datetime.fromtimestamp(int(time.time())).strftime('%d'))

        if f'[{dia}]' not in arq:
            logging.info(f" [{str(datetime.datetime.fromtimestamp(int(time.time())).strftime('%d'))}] ")

        elif arq[11:14] != dia:
            os.remove("teste.log")

    except Exception as e:
        print(f"\033[1;31;mmanage_log error: {e}\033[;;m")
