dynamically generating unique combo box and filling them with two different sources

Question

I want to dynamically generate Label on left & combos on the right in a grid

{'PHOTOSHOP': '6.5', 'NUKE': '7.0v9', 'MAYA': '2014', 'TESTING': '1.28', 'KATANA': '1.7', 'MARI': '4.0'} 
{'PHOTOSHOP': '10.5', 'NUKE': '6.3v6', 'MAYA': '2012', 'TESTING': '1.28', 'KATANA': '1.0', 'MARI': '1.0'}

my first problem is creating combos box in a way i can access them later outside the method based on name created at the time of for loop

from PyQt4 import QtCore, QtGui

class MainWindow(QtGui.QWidget):
    """docstring for MainWindow"""
    def __init__(self, dataIn1, dataIn2):
        super(MainWindow, self).__init__()
        self._dataIn1 =  dataIn1
        self._dataIn2 = dataIn2
        self.buildUI()

    def main(self):
        self.show()

    def buildUI(self):
        self.gridLayout = QtGui.QGridLayout()
            self.gridLayout.setSpacing(10)
        self.combo = QtGui.QComboBox('combo')
        for index, item in enumerate(self._dataIn1.iteritems()):
            # Below line doesn't work which i want to make work
            # objective is to assign unique name so i can access-
            # them later outside this method
            #self.item[0]+"_Combo" = QtGui.QComboBox()
            self.gridLayout.addWidget(QtGui.QLabel(item[0]), index, 0)
            # once uique combo is created I want to populate them from dataIn1 & dataIn2 lists
            self.gridLayout.addWidget(self.combo.addItems([item[-1]]), index, 1)
        self.setLayout(self.gridLayout)
        self.setWindowTitle('Experiment')

def main():
    app = QtGui.QApplication(sys.argv)
    smObj = MainWindow(dataIn1, dataIn2)
    smObj.main()
    app.exec_()

if __name__ == '__main__':
    main()

secondly I want to those combo box to be filled in by each Keys value from both dataIn1 and dataIn2 sources..

To dynamically create attributes, you can use setattr:

setattr(self, 'combo%d' % index, combo)

However, it's probably much more flexible to keep the combos in a list (then you can easily iterate over them afterwards).

Your loop should end up looking something like this:

    data1 = {
        'PHOTOSHOP': '6.5', 'NUKE': '7.0v9', 'MAYA': '2014',
        'TESTING': '1.28', 'KATANA': '1.7', 'MARI': '4.0',
        }
    data2 = {
        'PHOTOSHOP': '10.5', 'NUKE': '6.3v6', 'MAYA': '2012',
        'TESTING': '1.28', 'KATANA': '1.0', 'MARI': '1.0',
        }
    self.combos = []
    for index, (key, value) in enumerate(data1.items()):
        label = QtGui.QLabel(key, self)
        combo = QtGui.QComboBox(self)
        combo.addItem(value)
        combo.addItem(data2[key])
        self.combos.append(combo)
        # or setattr(self, 'combo%d' % index, combo)
        layout.addWidget(label, index, 0)
        layout.addWidget(combo, index, 1)
