🔒 Returning a custom error.

[stark geyser]

    async def add_profile(self) -> Profile | What goes here? :

        try:
            await self.connection.commit()
        except aiosqlite.IntegrityError as error:
            return error

        async with rows as cursor:
            result = await cursor.fetchone()
            if result is not None:
                return Profile(*result)
            else:
                # Return a custom error 
``` I've omitted some code to avoid some bloat, but I want to be able to return an error if I get a `aiosqlite.IntegrityError` and return an error if `if result is not None:` Where can I read about how I would do this?

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

I think Exception can work?

Profile | Exception

[pallid sky]

why would you return an error?

[pallid sky]

Profile | aiosqlite.IntegrityError | YourCustomError, but why do you want to return it?

[stark geyser]

So I can display to my user that something went wrong. Is that the wrong way to go about it?

[pallid sky]

it should be raised, and caught outside the function

in which case sure, you could print something custom

but don't return the error just to check if there is an error through non-idiomatic means

!e

class MyCustomError(Exception):
    pass

def f():
    raise MyCustomError

try:
    f()
except MyCustomError:
    print("womp-womp, something went wrong")

@pallid sky :white_check_mark: Your 3.12 eval job has completed with return code 0.

womp-womp, something went wrong

[stark geyser]

I see.

That makes a lot more sense than what I was gonna do 😆

Thank you
