re-importing modules

[T. Crane]

Hi,

When troubleshooting code that's saved in a text file, I often find that I
want to make a change to it, re-save it, then reimport it.  However, just
typing

import myTestCode

doesn't always seem to import the newer version.  Is it supposed to?  I find
that right now I often have to close my iPython window, then reopen it and
import my recently modified code.  I know this can't be the best way to do
this, but I don't know what is.

any suggestions/help welcome and appreciated,
