Not exactly sure what you mean, what would you call the ability to sort of, push a method call onto a thread like Invoke() in C# for example. Even if underneath the clean surface it posts the call into the message loop it gets the job done. > However, in GUIs there is usually some so called event-loop.

But lets say i'm not using a GUI. Or rather, for example in my WxPython application I have classes which needs to perform time consuming operations. I would _really_ not want to include lots of WX-stuff in an otherwise purely python class. I don't like mixing GUI code with other code, it feels very dirty. How would a python programmer(more experienced then I currently am) solve this? Should I implement some kind of message-loop-system in the class which the different threads "posts" to, and then the class(which is in the right thread) deals with any events "posted"? I'm spoiled from C# having everything delivered to me, so I'm confused as to how much I need to implement myself. Thinking perhaps there was some cute special python command I could use to do it for me :) P.S. Currently traveling far from home(but still I have programming on me brain), sorry for the delayed reply. -- http://mail.python.org/mailman/listinfo/python-list
