I've a problem: I want to get some integers from a json file and then check there if there are equals to the current date/month. But I've this error:

Unhandled exception in internal background task 'check_for_birthday'.

My function:

    @tasks.loop(seconds=1)
    async def check_for_birthday(self):
        now = datetime.datetime.now()
        curmonth = now.month

        with open(birthday_file, 'r') as f:
            var = jason.load(f)

                            else:
                                success = True

My json file:

{
    "712319703602692117": {
        "month": 12,
        "day": 12
    }
}

Can you help me ?

CodePudding user response：

Since var is a dictionary, for member in var: will iterate over its keys. From the docs:

iter(d)

Return an iterator over the keys of the dictionary. This is a shortcut for iter(d.keys()).

So in your case, member == "712319703602692117". Thus, member['month'] is an error because strings can only be indexed by integers and slices, not other strings.

You can iterate over key/value pairs using dict.items:

for key, member in var.items():
    ...

Here, member == {"month": 12, "day": 12}.
