PyQt GUI based CRUD application

I am new to the world of PyQt.I am using PyQt designer for designing the UI and coding to provide functionality in it.But unfortunately I am getting confused to link with the UI.By importing the class we generally doing in examples.But when I try my own code its not happening.

class Window(winBase, winForm):
   def __init__(self, parent = None)
     super(winBase, self).__init__(parent)
     self.setupUi(self)
