Golang Import Cycle Not Allowed

You may be using the method with the same name as the package look at the example to understand what I meant.

In PyGtk.go:

Package PyGtk

func PyGtk(){...}

In PyGtk_test.go: 

Package PyGtk

pygtk.PyGtk()// this is the issue you are already in the package PyGtk there is no need to use pygtk.PyGtk to access PyGtk()
