from turtle import Turtle
def tree(tList,length,angle,factor):
if length > 5:
lst = []
for t in tList:
t.forward(length);
temp = t.clone();
t.left(angle);
temp.right(angle);
lst.append(t);
lst.append(temp);
tree(lst,length*factor,angle,factor);
def makeTree(x,y):
t = Turtle();
t.color('green');
t.pensize(5);
t.hideturtle();
#t.getscreen().tracer(30,0);
t.speed(10);
t.left(90);
t.penup();
t.goto(x,y);
t.pendown();
t = tree([t],110,65,0.6375);
makeTree(0,0)
