Yes, but (didn't you expect that?) it loads imported files when it
first executes an import statement for them. Future import statements
will just get a reference to the loaded module, and won't reload
it. So after your application imports all the modules it needs, it
won't refer to the copies on disk again, after which it will be safe
for you to modify the on-disk copies.
Of course, you really ought to be working on a *copy* of the
application sources. When you're happy that your modifications are ok,
copy your development sources into production.
And finally, to force python to reload a module that it's already
loaded, use "reload(modulename)".
