You should start any new thread with a specification of the
versions of software you're asking about. Since you didn't,
I'll assume python version 2.7, PIL version 1.7, and Linux Ubuntu
version 14.04.

PIL is a package, whuch means it's a module containing other
modules., and contains modules such as Image. But that syntax
"from PIL import Image" doesn't tell you that. Any type of name
defined in module PIL can be retrieved by the from
syntax.
The way I can tell is either read the docs, or ask in the interpreter.
from PIL import Image
print type (Image)
<type 'module'>
That from syntax is roughly equivalent to
import PIL
Image = PIL.Image
And the leading capital I would have made me guess it was a class.
Thus I checked, using type ()

Modules don't have methods. open is an ordinary function in the module.

I don't understand the question. By using the from syntax, you
avoided having PIL in your namespace. If you wanted, you could
have said. import PIL. And used PIL.Image.open()
Can a module have another module inside it?
