Exception Handling guideline- Python vs Java

Question

I am original Java developer, for me, checked Exception in Java is obviously/easy enough for me to decide to catch or throw it to the caller to handle later. Then it comes P

Answer 1

OK, I can try and give an answer which I'll keep as neutral as it can be... (note: I have done Python professionally for a few months, but I am far from mastering the language in its entirety)

1. The guidelines are "free"; if you come from a Java background, you will certainly spend more time than most Python devs out there looking for documentation on what is thrown when, and have more try/except/finally than what is found in regular python code. In other words: do what suits you.

2. Apart from the fact that they can be thrown anywhere, at any moment, Python has multi-exception catch (only available in Java since 7), with (somewhat equivalent to Java 7's try-with-resources), you can have more than one except block (like Java can catch more than once), etc. Additionally, there are no real conventions that I know of on how exceptions should be named, so don't be fooled if you see SomeError, it may well be what a Java dev regards as a "checked exception" and not an Error.
