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_counterccsr|dkrng}|D]>}|�|�|��}|�|�|�|�|�|�|�|�qt|||||�D] }dVqbdS)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 cCstt�}|�d�|��|�d�|��dd�|�d�|��|�d�|� �t |gddd�}|D]}qjdS)Nr��Zi.��Agffffff�?)rZ setundobufferZ hideturtleZspeedZ getscreenZtracerrZpenuprZpendownr )r�trrrr�maketree's rcCst�}t�t�}d||S)Nzdone: %.2f sec.)�clockr)r�brrr�main5sr�__main__N) �__doc__Zturtlerr�timerrr rr�__name__�msg�printrrrr�s
