Parabola!

In this tutorial I will be changing this code (made by 유창희 on open processing) to python from java. This code prints out a program that draws a parabola using math functions.   

First things first, we are going to change void setup(){} and void draw(){} to def setup (): and def draw (): Than delete all the semi colons and 
indent everything following our setup and draw functions. 
Than we are going to change float angle, y; to angle = 1. We do this because in
python we d not need to declare these as floats, we only need to set a value to angle. 
Than we are going to add global angle right under  def draw (): We do this because 
in python when we add angle into the math function it is only searching for angle in the 
def draw (): function, but by adding global angle it knows to look outside the function. 
So far your code should look like this:     

Than we are going to change the color codes for background and fill to RGB codes. background will be background(255,248,237) and fill will be fill(255,149,149)After that we change angle++ to angle+=1 Your code should look like this:  

When you run it you should get a program that draws a parabola and finishes like this:
