Keeping a GUI responsive while running a lengthy process requires either some very elaborate "callbacks" to allow the GUI to process its message queue, or the use of (background) (worker) threads. Kicking off any number of threads to do some work usually isn't a problem. The fun starts wh...

Start with importing the library. from amqpstorm import Connection When consuming messages, we first need to define a function to handle the incoming messages.

The widely used combination of tic and toc can provide a rough idea of the execution time of a function or code snippets. For comparing several functions it shouldn't be used. Why? It is almost impossible to provide equal conditions for all code snippets to compare within a script using above solu...
