AttributeError: 'NoneType' object has no attribute 'format': y-coordinate: {0} above maximum of {1}.

st7565.Glcd#is_off_grid has an error in the error handling. it raises an error if it prints off screen.

the print function is implemented incorrectly (call format() on the string, not on the result of print).

error:

    y-coordinate: {0} above maximum of {1}.
    Traceback (most recent call last):
      File "/scratch.py", line 30, in <module>
        is_off_grid(100, 50, 10, 50)
      File "/scratch.py", line 26, in is_off_grid
        print('y-coordinate: {0} above maximum of {1}.').format(ymax, LCD_HEIGHT - 1)
    AttributeError: 'NoneType' object has no attribute 'format'
