Plugin build in python

Hi! I am trying to build a plugin in python. Can you send to me a Plugin example to be easier to me to build it. A Plugin reader and some Plugin with botons on the painel.

Thanks but I already tryed PythonAlgorithmExamples. And I only can find the superelipsoid plugin installed in paraview and the reader i cant find it. And i also needed a toolbar

Check also this earlier post that contains a python plugin that includes gui elements.

Hi! Thank you!
