i'm kinda new tkinter and i ran into a problem while using tkinter with python. I'm trying to get all of the buttons i have right now to take a number and add to it if the button is clicked or not, i ran into a wall and i have no idea how to fix it. Here's my code for reference.
from tkinter import *
class Application(Frame):

super(Application, self).__init__(master)
self.grid()
self.create_widgets()
def create_widgets(self):
Label(self,

self.is_itchy = BooleanVar()
Checkbutton(self,

self.story_txt = Text(self, width = 35, height = 5, wrap = WORD)
self.story_txt.grid(row = 10, column = 0, columnspan = 3)
Button(self,

self.story_txt.delete(0.0, END)
self.story_txt.insert(0.0, story)
root = Tk()
root.title("Joe's repair shop")

root.mainloop()
Here is the error i am getting

AttributeError: 'Application' object has no attribute 'oil'
On this line:
Checkbutton(self, text = "$26.00", variable = self.oil).grid(row = 2, column = 1, sticky = W)
You declare that the variable attribute of the Checkbutton widget should be equal to self.oil which you never give a value to, this throws an error as tkinter is trying to assign something which doesn't exist to this attribute.

I'm new to Python and just started venturing into doing GUIs. I created a Tkinter window that is pretty basic: it has 3 Entry bars and 3 File Dialog buttons. When you chose the 3rd directory, the GUI file automatically makes a call to a separate file and receives a large text block which is then displayed in a Text box.
The whole thing works correctly, but my problem is that after receiving and inserting the text response, Tkinter stops working and doesn't allow the user to scroll down.
I read that one reason this happens is because people use both .pack( ) and .grid( ), but I'm not mixing those two functions.
Thanks in advance for any help!
Here's my GUI file

In this file, I tried to return the value of employNum and employPass to the main function each time I clicked the display button. How can I do that?
from tkinter import *
def displayButton(root,employNum, employPass):
Label(root,text = employNum.get() ).grid(row = 3, column = 1, sticky = N+S+W+E)
Label(root, text = employPass.get()).grid(row = 4, column = 1, sticky = N+S+W+E)
def main():
root = Tk()
Label(root, text = 'Employee Number: ').grid(row = 0, column = 0, sticky = W)
Label(root, text = 'Login Password: ').grid(row = 1, column = 0, sticky = W)
employeeNum = StringVar()
employeePass = StringVar()
Entry(root, textvariable = employeeNum).grid(row = 0, column = 1, columnspan = 2, sticky = W)
Entry(root, textvariable = employeePass).grid(row = 1, column = 1, columnspan = 2, sticky = W)
checkButton = BooleanVar()
Checkbutton(root, text = 'Remember Me', variable = checkButton).grid(row = 2, column = 1, sticky = W)
Button(root, text = 'Save', relief = RAISED).grid(row = 2, column = 2, sticky = E)
display = Button(root, text = 'Display', relief = RAISED, command = lambda: displayButton(root, employeeNum,employeePass))
display.grid(row = 3, column = 2, sticky = E)
Label(root, text = "Employee's number is ").grid(row = 3, column = 0, sticky = W)
Label(root, text = "Employee's Passowrd is ").grid(row =4 , column = 0, sticky = W)
root.mainloop()
main()
Button can't return value using return. You can only set value in global variable or passed as argument. You can change text in Label assigned to global variable or passed as argument. You can create new Label but root have to be global variable or passed as argument.
I'm trying to add items to the listbox, but every time I try it, it's saying that the global name "title_input" is not defined. I don't understand why this doesn't work, because the last one that I did with this exact same structure didn't give me that error. I'm new to this, and the other tutorials and questions I read about global name errors didn't make sense to me. Thanks for the help!

self.add_title.grid(row = 16, column = 5, sticky = W, padx = 5, pady = 5)
self.title_input = Entry(self)
self.title_input.grid(row = 16, column = 4, sticky = W, padx = 5, pady = 5)
def add_item(self):
list.insert(END, title_input.get())

title_input is defined in your instance namespace but it is not defined in your global namespace. When you reference an unqualified title_input in your class method add_item, Python looks for title_input in the global namespace. When it doesn't find it there it gives you that error. Adding the self qualifier, self.title_input, to indicate that you wish to reference title_input in the instance namespace, will resolve the error.
I'm working on my final project for my computing I class.
The problem that I am having is:
When I click on the new entry button, hit the back button and click on the new entry button once again it does not work.
If you guys could tell me why that is?
The command on the button seems to be only working once. Thanks for your help.

In your entry function you overwrite self.entry, which is the name of the function, with a reference to a Label. When the button then calls self.entry it isn't function.
Simply call the Label something else.
i'm new to tkinter and I was trying to make a GUI where there was an image at the top with an area of 4 buttons underneath that image which would be a method of selecting answers. However with the code I have so far the buttons that I create just seem to stay in the top left corner and will not move under the image at all, does anybody know a solution to this please?
import Tkinter as tk
from Tkinter import *
from Tkinter import PhotoImage
root = Tk()
class Class1(Frame):
def __init__(self, master):
Frame.__init__(self, master)
self.grid()
self.master = master
self.question1_UI()
def question1_UI(self):
self.master.title("GUI")
gif1 = PhotoImage(file = 'Image.gif')
label1 = Label(image=gif1)
label1.image = gif1
label1.grid(row=1, column = 0, columnspan = 2, sticky=NW)
questionAButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionAButton.grid(row = 2, column = 1, sticky = S)
questionBButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionBButton.grid(row = 2, column = 2, sticky = S)
questionCButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionCButton.grid(row = 3, column = 3, sticky = S)
questionDButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionDButton.grid(row = 3, column = 4, sticky = S)
def main():
ex = Class1(root)
root.geometry("{0}x{1}+0+0".format(root.winfo_screenwidth(),
root.winfo_screenheight()))
root.mainloop()
if __name__ == '__main__':
main()
You are not using self as the parent of label1. Besides, the grid manager starts at row 0:
def question1_UI(self):
# ...
label1 = Label(self, image=gif1)
label1.image = gif1
label1.grid(row = 0, column = 0, columnspan = 2, sticky=NW)
questionAButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionAButton.grid(row = 1, column = 0, sticky = S)
questionBButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionBButton.grid(row = 1, column = 1, sticky = S)
questionCButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionCButton.grid(row = 2, column = 0, sticky = S)
questionDButton = Button(self, text='Submit',font=('MS', 8,'bold'))
questionDButton.grid(row = 2, column = 1, sticky = S)
