Uses: (1) a tree-generator, where the drawing is quasi the side-effect, whereas the generator always yields None. (2) Turtle-cloning: At each branching point the current pen is cloned. So in the end there are 1024 turtles. � )�Turtle�mainloop)� perf_counterc c sr |dkrng }| D ]>}|� |� |�� }|�|� |�|� |�|� |�|� qt||| ||�D ] }dV qbdS )z� plist is list of pens l is length of branch a is half of the angle between 2 branches f is factor by which branch is shortened from level to level.� N)�forwardZclone�left�right�append�tree)Zplist�l�a�fZlst�p�q�x� r �'/usr/lib64/python3.8/turtledemo/tree.pyr s r c C st t � } | �d � | �� | �d� | �� �dd� | �d� | �� | �d� | � � t | gddd�}|D ]}qjd S )Nr � �Z i.����� �A gffffff�?) r Z setundobufferZ hideturtleZspeedZ getscreenZtracerr Zpenupr Zpendownr )r �tr r r r �maketree' s r c C s t � } t� t � }d|| S )Nzdone: %.2f sec.)�clockr )r �br r r �main5 s r �__main__N) �__doc__Zturtler r �timer r r r r �__name__�msg�printr r r r �<module> s
