Pyside/Pyqt5 dynamically adding and sorting items

Question

I have a simple user interface where I want to dynamically add frames and labels in a widget (as I will use these labels to transmit a video feed from my webcams).

In the following code I set a function where the user selects an integer which represents the number of labels(webcams) they want to see and then dynamically adds these labels& frames to the widget:

def loopCamFeed(self,n):
    if (n % 2) == 0:
        dividnd = n / 2
        for i in range(2):
            self.frame_12 = QFrame(self.ui.webcamWidget)
            self.frame_12.setObjectName(u"frame_12")
            self.frame_12.setFrameShape(QFrame.StyledPanel)
            self.frame_12.setFrameShadow(QFrame.Raised)
            self.horizontalLayout_14 = QHBoxLayout(self.frame_12)
            self.horizontalLayout_14.setObjectName(u"horizontalLayout_14")
            for i in range(int(dividnd)):
                self.label_5 = QLabel("hello",self.frame_12)
                self.label_5.setObjectName(u"label_5")
                self.horizontalLayout_14.addWidget(self.label_5, 0, Qt.AlignHCenter)
                self.ui.verticalLayout_15.addWidget(self.frame_12)
    

Which displays the labels as in the image below:

--By adding a value of 2:

--By adding a value of 4):

By adding a value of 8:

The challenge that I am facing is how to handle an odd number selection. For example, if a user selects 3 or 7 webcams/labels.

If a user selects 3 labels/webcams, I'd want to show one on the top frame and two at the bottom.

Use a grid layout instead of a horizontal layout:

    def loopCamFeed(self,n):
    self.frame_12 = QFrame(self.ui.webcamWidget)
    self.frame_12.setObjectName(u"frame_12")
    self.frame_12.setFrameShape(QFrame.StyledPanel)
    self.frame_12.setFrameShadow(QFrame.Raised)
    self.grid_layout = QGridLayout(self.frame_12)
    self.grid_layout.setObjectName(u"grid_layout")
    for i in range(int(n)):
        self.label_5 = QLabel("hello",self.frame_12)
        self.label_5.setObjectName(u"label_5")
        self.grid_layout.addWidget(self.label_5, 0, Qt.AlignHCenter)
    self.ui.verticalLayout_15.addWidget(self.frame_12)
