Learn how while loop works in Python.

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, you might have made a mistake. In particular, remember to indent the contents of the loop!
