In the C++ equivalent of this example a check is made whether the vector (here in Python we have a list) actually has any lines in it that is whether the Hough lines function has managed to find any in the given image. This check is missing for the Python example and if no lines are found the application breaks.

All of these: (performance) Prefer prefix ++/-- operators for non-primitive types.

1. Following condition is True on each iteration becuase -1 % 0xFF is 255 not -1
code = cv2.waitKey(100) % 0x100
if code != -1:
break
this were resetting point position on each cycle not on key press as intended
2. Previous small bug were masking serious bug with matrix operation on matrices of incorrect size.
As the result on 2nd iteration of internal cycle program has crushed.
I have fixed it too, matrix operation was taken from examples/cpp/kalman.cpp where it looks like
randn( processNoise, Scalar(0), Scalar::all(sqrt(KF.processNoiseCov.at<float>(0, 0))));
which is something totally different from previous code here.
Example behave as it should now, i.e. point moving by circle trajectory as in C++ example.
