One reaction to <url: <url:http://preview.tinyurl.com/ProgrammingBookP3> has
been that turtle graphics may be off-putting to some readers because it is
associated with children's learning.
What do you think?
How about calling it Raptor Graphics that will please everyone ;-)
He he. :-)
import turtle as raptor
raptor.shape( "triangle" )
def draw_poison_bush( level, angle, stem_length ):
start_pos = raptor.pos()
raptor.left( angle )
raptor.forward( stem_length )
if level > 0:
draw_poison_bush( level-1, 30, 0.7*stem_length )
draw_poison_bush( level-1, 0, 0.85*stem_length )
draw_poison_bush( level-1, -37, 0.65*stem_length )
raptor.right( angle )
raptor.goto( start_pos )
raptor.title( "A DANGEROUS poison bush!" )
raptor.left( 90 )
raptor.back( 180 )
draw_poison_bush( 6, 0, 80 )
raptor.mainloop()
