Here is the quick sample:A better solution would be to "block" KeyboardInterrupt for the duration of the loop, and unblock it when it's time to poll for interrupts. From here, while the program is in the forever loop spamming away requests for data from my broker's API, using the CTRL-C keyboard interrupt function toggles the exception to the try loop, which nullifies the while loop, allowing the script to finalize the data saving protocol without bringing the entire script to an abrupt halt. 1.
