I’m having some trouble debugging an issue, I have an asyncio project and I would like it to shutdown gracefully. When I run my code and send a KeyboardInterrupt or TERM signal from a different screen, nothing seems to happen and it doesn’t look like clean_loop is being called. EDIT: I think I was able to isolate the problem a

How can I change the value of exiting when it is inside main()? Currently, the program always prints False no matter if I

The answers are pretty much all over the place, and I haven’t been able implement
Understanding scipy deconvolve
I’m trying to understand scipy.signal.deconvolve. From the mathematical point of view a convolution is just the multiplication in fourier space so I would expect that for two functions f and g: Deconvolve(Convolve(f,g) , g) == f In numpy/scipy this is either not the case or I’m missing an important point. Although there are some questions related to deconvolve on SO
What is the correct way to make my PyQt application quit when killed from the console (Ctrl-C)?
What is the correct way to make my PyQt application quit when killed from the console (Ctrl-C)? Currently (I have done nothing special to handle unix signals), my PyQt application ignores SIGINT (Ctrl+C). I want it to behave nicely and quit when it is killed. How should I do that?

In Perl I’d do this: How do I do the analogue of this in Python? Answer Register your handler with signal.signal like this: Code adapted from
