How to strech and rotate right half of an image?

I have an image of size (600, 300) made with the following code:

from PIL import Image, ImageDraw

im = Image.new('RGB', (600, 300), (255,255,255))
draw = ImageDraw.Draw(im)
draw.rectangle((0, 0, 600, 300/3), fill=(174,28,40)) #rood
draw.rectangle((0, 200, 600, 400), fill=(33,70,139)) #rood
im.save('result.jpg', quality=95)

The image has three horizontal stripes with different colors (red, white and blue) like this:

rrrrrr 
wwwwww
bbbbbb

I want to take the second half of the image and rotate it clockwise by 90 degrees.

rrrrwb
wwwrwb
bbbrwb

Can this be done in Python?

I was making the dutch/french flag combination

Using the help of HansHirse i could get my desired result, Namely a unison of the french and dutch flags.

from PIL import Image, ImageDraw

    im = Image.new('RGB', (600, 300), (255,255,255))
    draw = ImageDraw.Draw(im)
    draw.rectangle((0, 0, 600, 300/3), fill=(174,28,40)) #red
    draw.rectangle((0, 200, 600, 400), fill=(33,70,139)) #blue

    # the  rotation needs to be the other way around
    sub_image = im.crop(box=(300,0,600,300)).rotate(-90) # can use negative value
    im.paste(sub_image, box=(300,0)) # box=(0,300) to paste in front

    im.save('dutchFrench.jpg', quality=95)

enter image description here

Crop the right part of the image, rotate it by 90 degrees, and paste it back into the image. That all can be done in just one line:

from PIL import Image, ImageDraw, ImageOps

im = Image.new('RGB', (600, 300), (255, 255, 255))
draw = ImageDraw.Draw(im)
draw.rectangle((0, 0, 600, 300/3), fill=(174, 28, 40))
draw.rectangle((0, 200, 600, 400), fill=(33, 70, 139))

# Crop right part of image, rotate by 90 degrees, and paste back into image
im.paste(im.crop((300, 0, 600, 300)).rotate(90), (300, 0))

im.save('result.jpg', quality=95)

Result

Hope that helps!
