There was another topic in these forums recently about "un-importing"
modules (and how you can not do that reliably without restarting
python). There was various ways mentioned of keeping track of what was
imported. And there was mentioned reasonable ways of finding all
possible imports on a computer.
By "unused imports" I assume you mean "all unused imports in the
application's source code" as opposed to meaning "all unused modules/
packages/libraries on that computer."
Personally I'd love to see more tutorials on the AST module; An AST
for Dummies. Pretty much the tutorials talk about parsing an
expression like "1+2=3". But I'd like to see how blocks are compiled/
managed by the indent/dedent tokens and how the complete algorithm for
finding qouted strings is implimented (using really simple
explanations).
Some google buzzwords to help with your search for your question: sys
import cache, import hook, pydoc walkpackages().
And I just found this little tool; never knew about it: C:\PythonXX
\Tools\Scripts\pydocui.pyw
Yes I meant unused imports in each of the modules actually...
The problem for me is to actually understand what are all the possible
AST node that can involve the use of an actual import, and I didn't
find anything helpful aboupt that.
The ASDL definition says everything in theory but without some examples
is a bit hard.
I got something nice however:

But on windows and Python 2.5 nothing is working :/, even if I blandly
copied the
ast.py from the python 2.7 code file..
File "h:\long\path\devsonly\ast.py", line 166, in iter_fields
for field in node._fields:
TypeError: 'NoneType' object is not iterable
