Write a function doGraphics that will take a list as input. The function doGraphics will start by creating a canvas from the 640x480.jpg file in the mediasources folder. You will draw on the canvas according to the commands in the input list. Each element of the list will be a string. There will be two kinds of strings in the list:

• “b 200 120” means to draw a black dot at x position 200 and y position 120–(200,120).
The numbers, of course, will change, but the command will always be a “b.” You can assume that the input numbers will always have three digits.
• “l 000 010 100 200” means to draw a line from position (0,10) to position (100,200).
So an input list might look like: ["b 100 200","b 101 200","b 102 200","l 102 200 102 300"] (but have any number of elements).

Note: The important thing here is to iterate through the list’s items and handle each case with the “split” method.

```
def doGraphics (list):
canvas = makePicture("640x480.jpg")
for item in list:
if item[0]=="b":
parts = item.split(" ")
px = getPixel(canvas, int(parts[1]), int(parts[2]))
setColor(px, makeColor(0,0,0))
elif item[0]=="l":
parts = item.split(" ")
x1 = int(parts[1])
y1 = int(parts[2])
x2 = int(parts[3])
y2 = int(parts[4])
addLine(canvas, x1, y1, x2, y2)

return canvas
```
