Sometimes we have need to interact? with an application,for example by　marking points in an image,or you need to annotation some training data.PyLab comes with a simple function　ginput() the let's you do just that .Here's a short example.

            
from PIL import Image
from pylab import *
im = array(Image.open('test.jpg'))
imshow(im)
print 'Please click 3 points'
x =ginput(3)
print 'you clicked:',x
show()
          

This plots an image and waits for the user to click three times in the image region of the figures window.The coordinates[x,y] of the clicks are saved in a list x.
