Coordinates of curves with turtle module in python

[abhishek07]

How can i generate coordinates of curves using turtle module in python? I am a beginner in python.

you can see "The 50+ demo applications of the turtle module of Python are intended as examples for using Python and turtlegraphics in an educational setting." on this page - http://code.google.com/p/python-turtle-demo/. It`s interesting :)

To generate the coordinates of a curve, you need an equation. Then you substitute values in the equation. Here's an example:

from time import sleep
from turtle import *
 
def parabolaY(x, a=0.250, b=-10, c=0):
    return a*x**2 + b*x + c
 
pen = Pen()
pen.tracer(True)
pen.color('red')
pen.width(3)
pen.goto(0,0)
pen.down()
for x in range(0,51):
    pen.goto(x, parabolaY(x))
pen.up()
pen.goto(-100,-100)
pen.color('green')
pen.write("DONE!")
sleep(2)
pen._destroy()
