while True:
    # Get the gesture data
    gesture_data = flick.get_gesture_data()
# Check for specific gestures
    if gesture_data == flicklibrary.GESTURE_UP:
        print("Up gesture detected!")
    elif gesture_data == flicklibrary.GESTURE_DOWN:
        print("Down gesture detected!")
    elif gesture_data == flicklibrary.GESTURE_LEFT:
        print("Left gesture detected!")
    elif gesture_data == flicklibrary.GESTURE_RIGHT:
        print("Right gesture detected!")
# Wait for 0.1 seconds before checking again
    time.sleep(0.1)
```
Note: In the examples above, make sure to replace `flicklibrary` with the actual library name imported in your Python script.
