I set db_ID_1 to '0' with shelve module like pickle module.. i print db_ID_1 and it = 0 but when I do... IF db_ID_1 != '0': .. it think it isn't 0

pickle is just like Shelve, I'm using Python 3.10.7 VENV environment on visual studio code

it says db_ID_1 is 0 in the terminal but when it comes to.. if db_ID_1 != '0': .. it think it isn't a 0 so it runs the wrong bit of code...

any help is much appreciated !!!

if think the problem is maybe with the string '0' or the class ID_1_db: .... i need it to be a str not a float thx.

    time.sleep(1)

as it is a string I needed to add str before db_ID_1... str(db_ID_1)

if str(db_ID_1) != '0':
    try:
        status_order = exchange.fetch_order(id=str(db_ID_1), symbol=symbol)
