Z = zypp.ZYppFactory_instance().getZYpp()
Z.initializeTarget( zypp.Pathname("/") )
Z.target().load();

for item in Z.pool():
    if not item.status().isInstalled():
      continue
    
    print "%s:%s-%s.%s\t(%s)" % ( item.kind(),
                                  item.name(),
                                  item.edition(),
                                  item.arch(),
                                  item.repoInfo().alias() )
    if zypp.isKindPackage( item ):
      print " Group: %s" %(zypp.asKindPackage( item ).group( ) )

You could try to lookup the package in /var/log/zypp/history. The 'install' 
entry lists at least the alias of the repo the package came from. 

  2009-05-04 12:07:39|install|xteddy|2.0.1-40.126|i586|root@Fibonacci|
  repo-oss|ab35dda25455d04f872ad4bceba72b7aef621195

Unfortunately there seems to be no reader interface for the history file in 
libzypp. I suppose Jano implemented the reader for zypper only. There are  
HistoryItem datastructures, but I don't see methods to recreate them from the 
loglines. Nor any convenience to (reverse) iterate the history file.  Maybe 
Jano has some code that can be moved to libzypp, so we could offer a history 
reader in zypp and also the bindings.

The code won't help you. Look at the 'item.repoInfo().alias()' output in the 
above example. An installed packages repository is the '@system' repository, 
aka the rpm database, an not the repository package was installed from.
