Enabling and disabling custom wanings

[Steven D'Aprano]

I have a warning that my code generates using the warning module:

https://docs.python.org/3/library/warnings.html


def spam(n):
    if n < 10:
        warnings.warn("not enough spam!")
    return "spam" * n


By default, I want this warning to be disabled, but I want the user to be 
able to enable or disable that warning at runtime. This is the code I use:


def enable():
    warnings.filterwarnings("always",
              category=UserWarning, module=__name__)

def disable():
    warnings.filterwarnings("ignore",
              category=UserWarning, module=__name__)


Am I doing it right?
