Basic while loop

Below you can find the example from the video where the error variable, initially equal to 50.0, is divided by 4 and printed out on every run:

error = 50.0
while error > 1 :
    error = error / 4
    print(error)

This example will come in handy, because it's time to build a while loop yourself! We're going to code a while loop that implements a very basic control system for an inverted pendulum. If there's an offset from standing perfectly straight, the while loop will incrementally fix this offset.

Note that if your while loop takes too long to run, or your session is expiring, you might have created an infinite loop. In particular, remember to indent the contents of the loop using four spaces or auto-indentation, and make sure the conditions are such that the loop has a stopping point.
