Ok, that makes sense, however your example doesn't seem to work: TypeError: not all arguments converted during string formatting I'll keep playing with it... thanks for clarifying why the same gizmo was always loading in my example -----Original Message----- From: studiosysadmins-discuss-bounces@studiosysadmins.com [mailto:studiosysadmins-discuss-bounces@studiosysadmins.com] On Behalf Of Ott, Daniel Sent: Friday, April 27, 2012 12:26 PM To: discuss@studiosysadmins.com Subject: Re: [SSA-Discuss] While waiting to be added to the Foundry forums - python/nuke question lambda just returns an unnamed function...

That works! Your previous example got me thinking about evaluating the string, and this also works: for g in gizmoList: gizMenu = "nuke.menu( 'Nodes' ).addCommand( 'Gizmos/" + os.path.splitext(g)[0] + "', lambda: nuke.createNode('" + g + "') )" eval(gizMenu) Thanks for your help!
