Only the first example in this chapter uses the movie object. Rewrite any of the other example programs to create a movie object and return the movie object.
Note: For most examples this only involves adding the final two lines from program 170 onto the end of the example.
```
def movingRectangle2(directory):
for num in range (1 ,30): #29 frames
canvas = makeEmptyPicture (300 ,250)
#add a filled rect moving linearly
addRectFilled(canvas ,num*10,num*5,50,50,red)
# Let’s have one just moving around
blueX = 100+ int(10 * sin(num))
blueY = 4*num+int(10* cos(num))
addRectFilled(canvas ,blueX ,blueY ,50,50,blue)
# Now , write out the frame
# Have to deal with single digit vs. double digit
numStr=str(num)
if num < 10:
writePictureTo ( canvas , directory +"//frame0"+ numStr +".jpg")
if num >= 10:
writePictureTo ( canvas , directory +"//frame"+ numStr +".jpg")
movie = makeMovieFromInitialFile(directory+"//frame00.jpg");
return movie
```
