o Nj|c @s<dZddlTddZddZedkreeedSdS) aF turtle-example-suite: tdemo_round_dance.py (Needs version 1.1 of the turtle module that comes with Python 3.1) Dancing turtles have a compound shape consisting of a series of triangles of decreasing size. Turtles march along a circle while rotating pairwise in opposite direction, with one exception. Does that breaking of symmetry enhance the attractiveness of the example? Press any key to stop the animation. Technically: demonstrates use of compound shapes, transformation of shapes as well as cloning turtles. The animation is controlled through update(). )*cCsdadS)NF)runningrr(lib/python3.10/turtledemo/round_dance.pystopsrc Csttdtdtdd}d}d}d}td}td D]"}t|t}||9}||9}t| | ||d d|fd qt d |tdtd t t d dg}tdD]}t dtdtdt|dd krz|tq]tdatttd}trd} |D]} | d| d| | | d krdnd} q|dkrtdt||d9}ttsdS)NZgray10FZtriangleg}Rc?gy!"@Zcompound g?ZblackZmultitriri8 TgGz?zDONE!)Z clearscreenZbgcolorZtracershapeZShaperangeZ shapesizeZ get_shapepolyZtiltZ addcomponentZregister_shapeZpuZsetposfdltupdateappendZclonehomerZ onkeypressrZlistenright) fZphiscshipZdancerscstaZdancerrrrmainsb           r __main__N)__doc__Zturtlerr __name__printZmainlooprrrrs5
