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?
