[Tutor] Fastest way to iterate through a file

oh i want to bring something up, there is this one line which i think is
suggesting that there is a way to use this object that the document says
it's a lot faster than getdata and getpixel.
Allocates storage for the image and loads it from the file (or from the
source, for lazy operations). In normal cases, you don't need to call this
method, since the Image class automatically loads an opened image when it is
accessed for the first time.
(New in 1.1.6) In 1.1.6 and later, *load* returns a pixel access object that
can be used to read and modify pixels. The access object behaves like a
2-dimensional array, so you can do:
pix = im.load()
print pix[x, y]
pix[x, y] = value
Access via this object is a lot faster than *getpixel* and *putpixel*.
according to it, this load function is a new addition to 1.1.6, and this
object is different from the rest.
