if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    ex = Ui_Form()
    ex.show
    sys.exit(app.exec_())

end this is the error i get

Traceback (most recent call last):
  File "C:\Users\IT4PROGRESS\Desktop\2dehands gui\output.py", line 99, in <module>
    ex.show
AttributeError: 'Ui_Form' object has no attribute 'show'

i use python 2.7

Firstly, don't edit file generated by pyuic. Make another .py file and import it. That way, instead of trying to show() the generated UI file directly, you can make a QMainWindow based class that you can run show() on and it will build the generated ui file for you. Like this:

import sys
from PyQt4 import QtCore, QtGui
from Ui_Form import Ui_Form

class Main(QtGui.QMainWindow):
    def __init__(self):
        super(Main, self).__init__()

        # build ui
        self.ui = Ui_Form()
        self.ui.setupUi(self)

        # connect signals
        self.ui.some_button.connect(self.on_button)

    def on_button(self):
        print 'Button clicked!'


if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    main = Main()
    main.show()
    sys.exit(app.exec_())
