Hi all,
I am fairly new to python (ie < 2 years). I have a question about
pylint. I am running on windows 10/11, python 3.10.11.
[...]
if p.returncode >= 8:
raise Exception(f'Invalid result: {p.returncode}')
It actually runs fine. But pylint is not having it. I get:
win_get_put_tb_filters.py:61:12: W0719: Raising too general exception:
Exception (broad-exception-raised)
pylint is just a linter, ignore it if the code works and you like it the
way it is.
pylint complains because you use Exception. Use e.g. RuntimeException to
silence it.
^^^^^^^^^^^^^^^^
Ingrid says it's a RuntimeError, not RuntimeException.
Meanwhile, the purpose of this complaint from pylint (and notice it's a
"warning", not an "error", so take that for what it's worth), is that
you usually want to convey some information when you raise an exception.
Of course, you can put that into the message you pass to the class
instance you raise, but the type of exception is informational too.
Raising just "Exception" is equivalent to saying "my car is broken",
without specifying that the starter turns but won't "catch", or starts
but the transmission won't engage, or the battery is dead, or .... so
it's *advising* (not forcing) you to be more informative.
