How pass data from second window to main?

I have a python app that change mac address with pyqt5 GUI. I have two python files. The main python file (mainWindow.py) that run main program then I press button to open the second window from second python file secondWindow.py. In second python file opens a window entry then I have to put letters and numbers like then I have to pass data in the first main app label window.
Can anyone help me to solve that?
I tried to reduce code.

One solution would be to assign the MainWindow as the parent of the SecondWindow. Then to get the label text all the SecondWindow has to do is self.parent.label.setText('something'). See the minor adjustments I made below.
mainWindow.py
class Ui_MainWindow(object):
def specificWindow(self):
self.window = QtWidgets.QDialog()
self.ui = Ui_macSpecific()
self.ui.setupUi(self.window, self) # <--- assign MainWindow as parent to second window
self.window.show()
secondWindow.py
import macspoof_bash
class Ui_macSpecific(object):
def setupUi(self, macSpecific, master):
self.master = master
self.window = macSpecific
macSpecific.setObjectName("macSpecific")
macSpecific.resize(301, 140)
...
...
self.pushButton = QtWidgets.QPushButton(macSpecific, clicked = lambda: self.submit())
def submit(self):
print("submit")
text = self.lineEdit.text()
self.master.label_3.setText(text)
self.window.close()
config['ethernet']['wired_mac_address'] = text
with open("macspoof.ini", "w") as inifile:
config.write(inifile)

Embedding PyQtGraph plots within an existing Qt Window

I'm trying to embed PyQtGraphs into an existing Qt Window (designed with Qt Designer and converted to .py file). I'm having trouble getting the PyQt GraphicLayoutView to size correctly to the Qt Group which is also inside a Tab.
I had previously managed to get the plots to work using MatPlotLib but they are just too slow at updating once the dataset gets larger, so i decided to make the switch to PyQtGraph as several posts suggested.
Im unsure if im embedding the plots correctly or if it is a case of resizing the GrahpicLayoutView to fill the group.
Any help is appreciated, code and images attached:
Image showing how the graphicsView doesnt size to fit the group

AttributeError: 'ClassePrincipal' object has no attribute 'setObjectName'
But, I've been reading about this module, and there is this attribute.
Can someone help me, I'm realy noob about python, This is my firt program, and I have no idea what is happening.
Since now, thank you.
Ps: I used QT Designer.

As the error message implies, there is an error in line 17:
I guess you mistakenly wrote 'MainWindow.setObjectName' two times, but the first time without parameter. So Python is "thinking" you refer to an attribute with this name instead of a method and the underlying class does not have such an attribute (as described in the error).

I believe this file is generated by pyuic5. You should avoid editing computer generated file by hand. If you have .ui file you can try to generate py file using pyuic5 link below might help you out
http://pyqt.sourceforge.net/Docs/PyQt5/designer.html
Can you make your class extend QMainWindow and change the parts with MainWindow to self like below in setupUi. If this doesnt work create your file using Main Window option use -x flag on pyuic5 it will give you executable python code which is better option. also the link below should be helpful
self.setObjectName("MainWindow")
self.resize(464, 501)
http://www.rkblog.rk.edu.pl/w/p/simple-text-editor-pyqt4/

I did it, to fix that i just did
instead:
class ClassePrincipal(object):
I used
class ClassePrincipal(QMainWindow):
Thank you anyway.

Linking PyQt buttons with Python actions

I'm having trouble getting buttons in a GUI laid out in QT Designer and converted into a python script to do anything when clicked.
At the moment my code looks like this:
import sys
from PyQt4.QtGui import QApplication, QDialog
from punchmenuui import *
from PyQt4.QtGui import *
from PyQt4.QtCore import pyqtSignal
class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
self.closemenubutton.clicked.connect(self.closemenu)
def closemenu(self):
sys.exit()
app = QApplication(sys.argv)
window = QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(window)
window.show()
sys.exit(app.exec_())
As you can see, its simple. I have a button specified in the layout .py file and I'm trying to capture the "clicked" signal from it and have that trigger a clean exit event. The trouble is: nothing seems to achieve that.
I've tried both the newer and older style PyQt signal/slot bindings to no avail.
Can anyone spot what I'm doing wrong?
EDIT:
Thanks for the responses so far guys. I've tried every combination of all of your answers, but none of them work so far. My current code for the launcher .py script stands as:
import sys
from PyQt4.QtGui import QApplication, QDialog
from punchmenuui import *
from PyQt4.QtGui import *
from PyQt4.QtCore import pyqtSignal
class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
self.closemenubutton.clicked.connect(self.closemenu)
def closemenu():
sys.exit()
app = QApplication(sys.argv)
window = QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(window)
window.show()
sys.exit(app.exec_())
and the script for the QT-Designed ui is:

Does this help nail-down what isn't doing what it should be?

Your closemenu function needs to be part of your class.
class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setupUi(self)
self.closemenubutton.clicked.connect(self.closemenu)
# Notice this has been brought into the class
def closemenu(self):
sys.exit()
You didn't provide your UI file, so I can't perform an exact test, but I can show you that this works with a simple example:
This code creates a single button:
import sys
from PyQt4 import QtGui, QtCore
class Window(QtGui.QWidget):
def __init__(self):
QtGui.QWidget.__init__(self)
self.closebutton = QtGui.QPushButton('Exit', self)
self.closebutton.clicked.connect(self.exit_button)
layout = QtGui.QVBoxLayout(self)
layout.addWidget(self.closebutton)
def exit_button(self):
sys.exit()
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
window = Window()
window.show()
sys.exit(app.exec_())
It looks like this:
When the button is clicked, the application closes with an exit status of 0 (a clean exit)
C:\Sandbox>python exit_button.py
C:\Sandbox>echo %ERRORLEVEL%
0

Whatever the underlying problem was, I was able to remedy it by switching to using Eric IDE in conjunction with Qt designer and following this tutorial: http://eric-ide.python-projects.org/tutorials/MiniBrowser/index.html to learn about the benefits of a development "environment" over what amounts to basically notepad that I was using before!
Defining actions is so much easier when you can see the handles you're attaching them too!
Other noobs reading this - follow that guide, it got me off the ground with object orientated programming and GUIs.

After running the above python program it shows the window as:
But I have to assign the value from the line edit to the variable A and B so I can add them as:
sum = A + B
and I have show this value sum in the label Answer when we clicked on push button "Add" in above window, so please suggest proper change in above code.

You need to create a news action (ad_values in this case). Then, you need to connect this action to the Buttons signal (clicked for example). After the signal emits (i.e. the button is clicked), the actions reads the values from lineEdit and lineEdit_2, adds them up and set's the text of the label_2-widget (you might convert the values to int before [see the other answer for a simple implementation])
