Also no warning is shown for the given example:

from pywikibot.exceptions import UploadWarning

Isn't this a duplicate of T127998?

Or only in Python 2 like in T132261?

@Dvorapa, I don't know about the other two tasks. They lack the information needed on how to reproduce the issue.

@Dalba You're right, there are no steps to reproduce given.

Works for me.

Note that in python 3.2+ DeprecationWarnings are ignored by default. One has to change the default filters either via the command line:

$ python -Wd::DeprecationWarning test_module.py

or from within the code:

from warnings import simplefilter
simplefilter('default', DeprecationWarning)
from pywikibot.exceptions import UploadWarning

I get only Warning: without any warning message.

Are you running the code in the interpreter prompt or are you executing a python module? Anyway, I think it's a different issue and is worth opening a new task for. But you may re-open this one if you think it's more appropriate.

I created the new task: T184368: No deprecation warning is issued in the interpreter prompt for `from pywikibot.exceptions import UploadWarning`
