Why can't I import this?

I just discovered something for Tkinter that I want to use.
It's a 
Tooltip class, at <http:/
/tkinter.unpythonic.net/wiki/ToolTip> .

I've copied it to a file I named toolTipDemo.py and put it
with a 
couple of other files I use as modules. They're in
E:Python25Libsite-packagesmine. One file there is
intSpell.py, 
and I can import it by

from mine.intSpell import intSpell

With no problem:
 >>> from mine.intSpell import intSpell
 >>>
However, the same method of importing doesn't work with
toolTipDemo:
 >>> from mine.toolTipDemo import toolTipDemo
Traceback (most recent call last):
   File "<string>", line 1, in
<string>
ImportError: cannot import name toolTipDemo

I've tried various things, such as remarking out the whole
demo at 
the bottom, but leaving

if __name__ == '__main__':
     #demo()
     pass

Any ideas on what I've done wrong?

BTW, toolTipDemo.py runs fine at the command line. I.e., the
demo 
shows up nicely, with 2 tooltips.

Thanks,

Dick Moores

Try
from mine.toolTipDemo import demo

mine.toolTipDemo points to the module, then you need to
reference a name 
defined in the module. (You must have something called
intSpell in 
intSpell.py.)

Interestingly (or not) it just hit me that I should try
that, and it 
worked. So I suppose that if I want to use tooltips in a
Tkinter 
program, I can just use  "from mine.toolTipDemo import
*" and use 
what I need. (Haven't tried that yet, however.)

Thanks, Kent.

Yes, you can do that but in general that style is not
recommended. It 
makes it hard to figure out where names are defined and you
can import 
more than you really want. Better is to just import what you
want, e.g.
from mine.toolTipDemo import A, b, CC

or import the module with an alias:
import mine.toolTipDemo as TTD

then refer to e.g.
TTD.demo()

Thanks, Kent. Turns out all I needed was the class, ToolTip.
So just

from mine.toolTipDemo import ToolTip

will do it.

A good trick.

Thanks very much, Kent.

Dick
