Holy fuck whoever was in charge of setting up that disaster recovery needs a million dollar bonus. I get that they're managing $80B and this should all be standard but people usually don't listen to IT and take DR seriously. And even if you do set it up, are you going back to check that your backups are functioning properly and have alarms for when it messes up
Day 598 of asking for a way to tell which functions throw exceptions in Python so I can know when to wrap in try catch. Seems to me that every other language has this, but when I've asked for at least a linter that can tell me I'm calling a function that throws, the general answer has been "why would you want that?"
How am I supposed to ask for forgiveness if it's impossible to know that I'm doing something risky in the first place?
Do you have a specific PEP you're referencing or is this one of those "I assume this must be the case because of how common using try/except statements for flow control are" kind of things?
Like most things in life, context matters. In the OP it seems like the check function is used specifically so it could raise a PaymentException if the payment hasn't been received... That's not a "forgiveness/permission" context, this is a yes or no question, hence should have been an if.
If you're trying to confirm things like account existence/deletion, there's often no "account exists" function to return true or false. You just have to figure out the specific exception thrown and catch that specific one.
The worst are libraries that don't give specific exceptions, so you have to catch all exceptions then do extra work to tell what the specific situation is. Does the account not exist, or is the system unreachable?
