One way is to take advantage of the fact that the splash screen is just
a widget. You can just create a progress bar as a child widget and update

For example:

app = QApplication(sys.argv)

# Create a pixmap - not needed if you have your own.
pixmap = create_pixmap(480, 320)

splash = QSplashScreen(pixmap)
progressBar = QProgressBar(splash)
progressBar.setGeometry(splash.width()/10, 8*splash.height()/10,
                        8*splash.width()/10, splash.height()/10)

for i in range(0, 100):

    # Do something which takes some time.
    t = time.time()
    while time.time() < t + 0.1:

I hope this is enough to help you get started.
