python - from PyQt4 import QtGui ImportError: cannot import name 'QtGui' -

i'm new ui design using qt - installed qt , pyqt4 wrapper.

i have 'hello world' type script here:

import sys  pyqt4 import qtgui   def main():      app = qtgui.qapplication(sys.argv)      w = qtgui.qwidget()     w.resize(250, 150)     w.move(300, 300)     w.setwindowtitle('simple')     w.show()      sys.exit(app.exec_())   if __name__ == '__main__':     main() 

yet error:

c:\python34\python.exe c:/users/me/desktop/python/testqt.py traceback (most recent call last): file "c:/users/leo/desktop/python/testqt.py", line 2, in pyqt4 import qtgui importerror: cannot import name 'qtgui'
