Actually I was just teasing you about saying 'IDLE, which _importants_ 
many modules' instead of 'imports.'

It's not *how* IDLE imports the module, but that fact that IDLE imports the 
module before his script would be executed. For example:

### sys.py ###
path = "Hello"


### test.py ###
import sys

print sys.path


Save sys.py and test.py in the same directory. Run test.py from the command 
line. Then open test.py in IDLE and run it in IDLE. You should get two 
different results because IDLE imports sys as part of it's own code and 
python does not re-import modules. However, when you run test.py from the 
command line, sys has not been previously imported and our own sys.py is 
imported.

Hope this explains my reasoning.

If the module has been imported before your code is run, it will be the 
library module (very important if working in IDLE which importants many 
modules, for example). But if it has not been imported before, the module in 
the current directory is imported first. You can check if a module has been 
imported previously by checking if in sys.modules.

I'm pretty sure that the one in the current directory gets imported first. 
However, it is much simpler to just change the name of the module in the 
current directory.

The local one. sys.path has the list of directories that are searched 
for imports, in the order they are searched. The local directory is first.

You can look at the __file__ attribute of a module to see where it comes 
from, e.g.
import mymodule
print mymodule.__file__
