Using Curve objects

This test program is in the main function of curve.py. Uncomment out portions of the function as you implement methods in the Curve class. The full function graphs the function f(x) = x^3 - 15x.

def main():
  curve = Curve()
  print(curve)
  x=-5
  while x <= 5:
    curve.add_point(x, x**3 - 15*x)
    x += 0.05
  print(curve)
  #curve.set_color("green")
  #print(curve)

  #win = GraphWin("Testing Curve class", 1000, 1000)
  #xmin = curve.get_min_x()
  #xmax = curve.get_max_x()
  #ymin = curve.get_min_y()
  #ymax = curve.get_max_y()
  #print("%.2f, %.2f, %.2f, %.2f" % (xmin,ymin,xmax,ymax))
  #win.setCoords(xmin,ymin,xmax,1.2*ymax)
  #curve.draw(win)

  #win.getMouse()
  #baseline = curve.get_baseline()
  #baseline.set_color("red")
  #baseline.draw(win)

  #win.getMouse()

if __name__ == "__main__":
  main()

Go ahead and run python3 curve.py. The program should now print out basic information for a Curve object that has no points, then (since you added points) print out information for a Curve object that has several points, representing the curve f(x) = x^3 - 15x.

$ python3 curve.py
