우리가 passwordmissing1stscreen에서 P1 = self.entrypasswordmissingscreen1.text()을하는 대신 완벽하게 작동하는 솔루션 우연히 친구와 다른 동료 프로그래머 일부 논의 후, 그래서

    self.entrypasswordmissingscreen1 = QtWidgets.QLineEdit() 
    P1 = self.entrypasswordmissingscreen1.text() 
    #conections 
    self.cancelbutton.clicked.connect(self.exit) 
    self.okButton.clicked.connect(self.passwordmissing2ndscreen)

def passwordmissing2ndscreenverify(self): 
    P1=self.entrypasswordmissingscreen1.text() 
    P2=self.entrypasswordmissingscreen2.text() 
    print (P1) 
    print (P2)
