I hope this helps . first convert it to an iterator, then call next(my_iterator) each time you want the next thing
code :
from itertools import cycle
class Whatever:
    fnames = cycle(["im1.gif","im2.gif","im3.gif"])
    def on_button(self,*args,**kwargs):
        if self.sender().objectName() == "next_button":
           next_path = os.path.join("data", "images", next(self.fname))
           myPixMap = QtGui.QPixmap(next_path)
           ...
from Tkinter import *
from itertools import cycle
#from tkinter import ttk
def on_button():
    label.set(next(names))

root = Tk()
root.title("Iterator")

mainframe = Frame(root)
mainframe.grid()
names = cycle(["im1.gif","im2.gif","im3.gif"])
label = StringVar()
label.set("Click Next To Cycle Through")
Label(mainframe, textvariable=label).grid(column=2, row=2, sticky=(W, E))
Button(mainframe, text="next", command=on_button).grid(column=3, row=3, sticky=W)

for child in mainframe.winfo_children(): child.grid_configure(padx=5, pady=5)


root.mainloop()

wish of those help You wanted to add more forms when the "Add a new form" button is clicked? We can achieve this using Javascript. But i'll be teaching you how to do it using a Javascript library called jQuery.
First, download the library here.
code :
<script src="jquery-1.9.1.min.js"></script> <!-- CHANGE THE NECESSARY FILE DEPENDING ON THE VERSION YOU HAVE DOWNLOADED -->
<script>

  $(document).ready(function(){ /* PREPARE THE SCRIPT */       
    $("#add").click(function(e){ /* WHEN ADD BUTTON IS CLICKED */
      e.preventDefault(); 
      $(".jumbotron").append('First Name: <input type="text" name="firstname[]"><br>Last Name: <input type="text" name="lastname[]"><br>'); /* APPEND TWO MORE FIELDS */
    });

  });
</script>

I wish this help you Implemented signals and slots and now you will get idea how you can handle it
And mixing imports is not really a good idea
code :
from PyQt4 import QtCore, QtGui
import sys

class EditButtonsWidget(QtGui.QWidget):
    editCalled = QtCore.pyqtSignal(str)
    def __init__(self, row, col, parent=None,):
        super(EditButtonsWidget,self).__init__(parent)
        self.row = row
        self.col = col
        self.parent = parent
        btnsave = QtGui.QPushButton('Save')
        btnedit = QtGui.QPushButton('edit')
        btndelete = QtGui.QPushButton('delete')
        layout = QtGui.QHBoxLayout()
        layout.setContentsMargins(0,0,0,0)
        layout.setSpacing(0)
        layout.addWidget(btnsave)
        layout.addWidget(btnedit)
        layout.addWidget(btndelete)
        self.setLayout(layout)
        btnedit.clicked.connect(self.getAllCellVal)

    @QtCore.pyqtSlot()
    def getAllCellVal(self):
        itmVal = {}
        for col in range(0, 4):
            itm = self.parent.item(self.row, col).text()
            itmVal[col] = str(itm)
        if itmVal:
            self.editCalled.emit(str(itmVal))


class MainForm(QtGui.QDialog):
    def __init__(self,parent=None):
        super(MainForm,self).__init__(parent)
        self.resize(400,200)
        self.tableWidget = QtGui.QTableWidget()

        layout = QtGui.QVBoxLayout()
        layout.addWidget( self.tableWidget)
        self.setLayout(layout)
        self.init_main_form()

    def bb(self):
        button = QtGui.QApplication.focusWidget()
        index = self.tableWidget.indexAt(button.pos())
        if index.isValid():
            print(index.row(), index.column())

    def printEditVal(self, values):
        print values

    def init_main_form(self):
        data =[['a','b','c','d'],['z','y','x','w']]
        self.tableWidget.setColumnCount(5)
        for row in data:
            inx = data.index(row)
            self.tableWidget.insertRow(inx)
            self.tableWidget.setItem(inx,0,QtGui.QTableWidgetItem(str(row[0])))
            self.tableWidget.setItem(inx,1,QtGui.QTableWidgetItem(str(row[1])))
            self.tableWidget.setItem(inx,2,QtGui.QTableWidgetItem(str(row[2])))
            self.tableWidget.setItem(inx,3,QtGui.QTableWidgetItem(str(row[3])))
            buttonWid = EditButtonsWidget(inx,4, self.tableWidget)
            buttonWid.editCalled.connect(self.printEditVal)
            self.tableWidget.setCellWidget(inx,4,buttonWid)


def main():
    app = QtGui.QApplication(sys.argv)
    main_form = MainForm()
    main_form.show()
    app.exec_()
if __name__ == '__main__':
    main()
Label Increment on Button Click with For Loop C#

Label Increment on Button Click with For Loop C#

To fix this issue When the button is clicked, you change the value of the label, incrementing its current value.
This solution uses the % Operator (C# Reference)
code :
private void bttnAdd_Click(object sender, EventArgs e)
{
    int currentValue;
    // Tries to parse the text to an integer and puts the result in the currentValue variable
    if (int.TryParse(lblBet.Text, out currentValue))
    {
        // This equation assures that the value can't be greater that 5 and smaller than 1
        currentValue = (currentValue % 5) + 1;
        // Sets the new value to the label 
        lblBet.Text = currentValue.ToString();
    }
}
int currentValue = 1;
int remainderCurrentValue = currentValue % 5; // Equals 1
int increasedCurrentValue = remainderCurrentValue + 1; // Equals 2
int currentValue = 5;
int remainderCurrentValue = currentValue % 5; // Equals 0
int increasedCurrentValue = remainderCurrentValue + 1; // Equals 1
