This is my code. The code in email_compare() is my problem. I want it to take the input from the email box and compare it to the emails in my Sqlite database using a linear search. The problem is that though the input is exactly the same it won't output that it is correct. I have had to delete certain parts of my code due to having more code than writing so if it is required I will right back to say what I have deleted. Also I am not sure if you can turn Sqlite records into variables that can actually be compared so if there is another way of doing this then I would greatly appreciate being told how to do it in that method instead of what I am trying to do now.

I wrote a program that adds two numbers entered by the user into QLineEdit.
The result of the addition is output to the console in Pycharm.
How to make the result output to the application itself? (so that the user can see the answer).
I guess that there is some special method for this, but what is it?

How to make the result output to the application itself?
It's not magic. You just have to create a widget that will display the answer. Then set the text on that widget when you do the calculation.
self.answerLabel = QtWidgets.QLabel(self.widget)
def cal(self, Probnei):
val_1 = self.First_n.text()
val_2 = self.Second_n.text()
res = int(val_1) + int(val_2)
self.answerLabel.setText(res)
So, I want to close the function on_click_on_start which has while loop in it. And, dont want to close the window after hitting the stop button. Right now, I was using sys.exit() which crashed the program for some reason but, when I used only quit() it was closing the entire app. I am doing this on pyQt5. I am noob to GUI so please help me out. This is extra text which I have added so that I can post the question. Please ignore this.

Generally using variables is easiest way to manage status. You can use variable for update running status.
running_status = false
Use like
self.running_status = true
in on_click_on_start.
Use
self.running_status = false
in on_click_on_stop. So now you can call your function if running_status is true.
I have 2 windows, MainScreen and AddFW.
Whenever I go from MainScreen -> AddFW, it works (the MainScreen hides and the AddFW appears).
But when I try going back from AddFW to MainScreen, the window crashes and I get an error: "NameError: name 'AddFW' is not defined".
What am I doing wrong?

This happens because Add_FW exists only within the setupUi and retranslateUi methods. It works in MainWindow because you are declaring it below in
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
MainWindow = QtWidgets.QMainWindow() <- HERE
ui = Ui_MainWindow()
ui.setupUi(MainWindow)
MainWindow.show()
sys.exit(app.exec_())
One quick fix is to pass the AddFW object through connect this way :
self.Back.clicked.connect(lambda: self.BackToMain(AddFW))
But a better way to deal with this would be to inherit QMainWindow in both Ui_AddFW and Ui_MainWindow class due to which they both become an instance of QMainWindow and you wont have to pass the QMainWindow when you are instantiating it.
Check this out: PyQt class inheritance
Finally,
Instead of showing and hiding screens within each object, I would suggest creating a main.py and handle the show/hide logic there this way:
main.py
from AddFW import Ui_AddFW
from MainScreen import Ui_MainWindow
def handle_back_to_main():
add_fw.hide()
main_screen.show()
def handle_back_to_add_fw():
main_screen.hide()
add_fw.show()
add_fw = Ui_AddFW()
main_screen = Ui_MainWindow()
add_fw.Back.clicked.connect(handle_back_to_main)
main_screen.AddFWBtn.clicked.connect(handle_back_to_add_fw)
Using PyQt5 QPlaintext to store variables. Example AO = userinput?
What I have so far minus the GUI setup. I need to store it as simple variables so i can output to a DOCX. I know I have to manually user input for every QPlaintextbox available. would I use the getText(), link it to the push button to generate the variables. Thank you for your time.

as I see on your code, to get string from the QLineEdit you can use this code.
self.num.text()
if you print that code, it will automatically print the inputed string of QLineEdit.
you can add a QPushButton then make a signal slot to do that as a form in commonly use.
like these:
self.button = QPushButton()
self.button.clicked.connect(self.getLineEdit)
def getLineEdit(self):
lineEditText = self.num.text()
print(lineEditText)

Getting an error while trying to close and open current dialog window in python
I need to open and close two windows in loop.
also attaching the error that i got.
enter image description here
The reason of the error is that Dialog is not available in scope of loginCheck method and need to be passed explicitly as a param in the following line:
self.pbtn_signin.clicked.connect(self.loginCheck)
Here is the question with the answers, how to do it.
One of the options would be import partial from functools:
from functools import partial
And use this function to pass Dialog to loginCheck:
self.pbtn_signin.clicked.connect(partial(self.loginCheck, Dialog))
