My A-level project is an alarm system I have built using Tkinter that calculates the nearby traffic and changes your alarm time depending on how much the traffic will slow down or increase your journey.
I have calculated all the times I need, however, now I face the problem of having to constantly poll the current time to check it against my own, but this stops my tkinter functions from running. I am now fearing I should have used a different object orientated language.
How can I run these functions at the same time?
My code is below (I'm sure it is very inefficient).
