Drawing Bezier Curves in Python

CodeProject I found a great algorithm in Python that draw the Bezier curve (more about Bezier curve HERE) defined by a set of control points.
You can find the original algorithm HERE and my opinion about it is that its brilliant but I had an objection on it. I didnt like the ideea of defining the control points in source code, I wanted to input the number of control points and the values after xOy axis.
So... I made some changes:

• I deleted the initialization of controlPoints from doDrawing(...) function;
• I created a new function def inputpoints() in which I input the number of controlPoints and the xOy coordinates and I declared globally the variable controlPoints:

def inputpoints():

global controlPoints

        print("nr of points")

nr=int(input())#nr of points

controlPoints=np.zeros((nr,2),int)   

for i in xrange(nr):

controlPoints[i][0]=int(input())

controlPoints[i][1]=int(input())

• I added a new line inputpoints() before main(sys.argv[1:])

And the result is:

PS: I wont put the code because it isnt mine but if you want to try the original code or to try it with my modifications, you have a link at the beginning of this article!
