import sys pyqt5.qtcore import qcoreapplication pyqt5.qtgui import * pyqt5.qtwidgets import *  class window(qmainwindow):      def __init__(self):         super(window, self).__init__()         self.setgeometry(50, 50, 700, 600)          self.home()      def home(self):         test1choices = ['test1:','choice1', 'choice2', 'choice3', 'choice4','choice5', 'choice6', 'choice7', 'choice8', 'choice9']         test2choices= ['test2:','1','2','3','4','5','6','7','8','9','10','11','12','13','14','15']         in range(0,10):             choice1combobox = qcombobox(self)             choice1combobox.additems(test1choices)             choice1combobox.resize(150,25)             choice1combobox.move(30,(150+(i*35)))             choice1combobox.setcurrentindex(2)              choice2combobox = qcombobox(self)             choice2combobox.setobjectname("choice2combobox"+str(i))             choice2combobox.additems(test2choices)             choice2combobox.resize(75,25)             choice2combobox.move(200,(150+(i*35)))             choice2combobox.setcurrentindex(2)             choice2combobox.activated[str].connect(self.dosomething)              numtextbox = qlineedit(self)             numtextbox.setobjectname("numbox"+str(i))             numtextbox.move(325,(150+(i*35)))             numtextbox.resize(35,25)              result1textbox = qlineedit(self)             result1textbox.setobjectname("result1box"+str(i))             result1textbox.move(400,(150+(i*35)))             result1textbox.resize(100,25)             result1textbox.setenabled(0)              result2textbox = qlineedit(self)             result2textbox.setobjectname("result2box"+str(i))             result2textbox.move(525,(150+(i*35)))             result2textbox.resize(100,25)             result2textbox.setenabled(0)          self.show()      def dosomething(self):         numbers=['result1','result2','result3','result4','result5','result6','result7','result8','result9','result10','result11','result12','result13','result14','result15']  def run():     app = qapplication(sys.argv)     gui = window()     sys.exit(app.exec_())   run() 

to summarize bring in index of selected qcombobox. use index number reference answer in "numbers" array. print result in qlineedit in same row

we use sender() object emits signal, name of object setobjectname(), , search index, other objects findchildren(), example output union of selected texts.

add name choice1combobox:

choice1combobox.setobjectname("choice1combobox"+str(i)) 

dosomething function:

def dosomething(self, _):     sender = self.sender()      l = sender.objectname().split("choice1combobox")     if len(l) > 1:         number = l[1]     else:         number = sender.objectname().split("choice2combobox")[1]      combo1 = self.findchildren(qcombobox, "choice1combobox"+number)[0]     combo2 = self.findchildren(qcombobox, "choice2combobox"+number)[0]     obj = self.findchildren(qlineedit, "numbox"+number)[0]     obj.settext(combo1.currenttext() + " " +  combo2.currenttext())
