i've run into a problem with tkinter, where i'm unsure of how to tell what frame the user is in, and save that to a variable. i need (i think) this information to be able to switch between multiple frames.
def check(value): # checks to see if the button that was click was the correct answer
if value:
print("you picked the right answer!")
answers.increase()
frame1.grid_remove()
frame2.grid(row=5)
else:
print("sorry thats not right")
frame1.grid_remove()
frame2.grid(row=5)
this function is called by a button like:
q1choice1 = Button(frame1, height=2, width=50, text=question1[1].text, command=lambda: check(question1[1].value))
q1choice2 = Button(frame1, height=2, width=50, text=question1[2].text, command=lambda: check(question1[2].value))
q1choice3 = Button(frame1, height=2, width=50, text=question1[3].text, command=lambda: check(question1[3].value))
q1choice4 = Button(frame1, height=2, width=50, text=question1[4].text, command=lambda: check(question1[4].value))
instead of frame1.grid_remove and frame2.grid i would like to be able to have a variable such as x.grid_remove() y.grid(row=) so that this on function can switch between all frames. i can post the rest of the code if it's needed but i tried to just keep it to what is relevant.
thanks,

mainloop()
Why don't you try to set the variable every time the frame changes, so in the code that changes the frame add another parameter, in the function which will take the name of the frame and then in the function it will set a (Global??) variable to that name which can be read at any time?
so for example
def change(..., newFrame):
global curFrame
curFrame = newFrame
change() being the function in which you use to change the frame to another
This will be added to the function you use to change the frame, and this will make use of a global variable which can be read any where, which you set to hold the value of the frame you change to when you change it

I'm trying to program an interface with tkinter, that shows users of my application as a list of Labels. The list is created from a database (created with sqlite3).
By clicking on each Label the program should open another window, showing details of the clicked user.
maybe do I need to use classes? (because for now, my script is not OOP)
root = Tk()
root.title("Utenti")

thanks for helping!
I have a spreadsheet that records my income and expenses, with dates, description, debit and credit amount. I wanted to used openpyxl to automate the process of adding values that are in a particular category, the program kind of works now, but the problem is: when I am searching for a phrase that don't exist in the sheet, the program crash, it can not do the things it suppose to before and after the search phrase that dont exist.
for example,
when i wanted to calculate the subtotal of search phrase "wage" and the put the subtotal into a target cell, it works fine. the problem comes out when i ask the program to look for something that isnt there.
I ask the program to look for wage, and create a subtotal, works fine and suppose to store the value at a defined target, when i ask the program to look for tax (which dont exist) the program showed nothing, then i ask the program to get the subtotal of rent (which exists). The program cant make the changes.
i am relatively new to all this.... so thanks again for helping! :)

try:

except:

And run your code inside of this from which you want to skip the error with this try except. if any exception happened then it will ignore this and will be running.
I want to have a GUI with 2 buttons. Once clicked on either button, I want to see a new GUI which has a button to go back to the main GUI with the two buttons again.
This is what I've got right now but the 'Go back' button doesn't do anything. How can I go back to my first page using tkinter?

It does work, expand your screen a bit. The frames get added below.

slechtekeuze.grid(row=0, column=0, columnspan=2)
# Option to got back

You can store the values for each number in seperate IntVar variables, then get the values of these variables inside the solver function and perform all the operations that are in your second code. The code should be modularised with the use of a class containing functions that create the widgets and run the solver code. To read more about class-based declarations in Tkinter, read this.

A few things that you can change/try:
Keep the "Entry" variables unique. Then extract each number using .get() command.
Use lambda in the command options of the Button as follows:
command = lambda: solver(num1, num2, num3, num4)
And if you want to display your returned number from 'solver', grid a Label in your tkinter window. Then use Label.config(text="Your number here") to show it in your tkinter window
I'm trying to create a program in where you put a word in a box, press add, and this word goes to a list, which is also displayed on the right side. When I press the forward button the first thing on the list is deleted. Problem is I can't get the labels to update when I press the buttons / edit the list.
from tkinter import *
root = Tk()
root.title('Speakers List')
root.minsize(800, 600)
speakers = ['none']
spe = speakers[0]
def add():
if spe == 'none':
speakers.insert(0, [s])
e.delete(0, END)
spe.config(text=speakers[0])
else:
speakers[-2] = [s]
e.delete(0, END)
spe.config(text=speakers[0])
return
def forward():
if len(speakers) is 0:
return
else:
del speakers[0]
spe.config(text=speakers[0])
return
entry = StringVar()
e = Entry(root, width=30, font=("Arial", 20), textvariable=entry)
e.grid(row=0, sticky=W)
s = e.get()
button1 = Button(root, padx=10, pady=10, bd=5, text='Add', fg='black', command=add)
button1.grid(row=0, column=1)
button2 = Button(root, padx=10, pady=10, bd=5, text='Next', fg='black', command=forward)
button2.grid(row=1, column=1)
n = Label(root, font=("Arial", 35), bd=2, text=spe)
n.grid(row=1, sticky=W)
listdisplay = Label(root, font=('Arial', 20), text=speakers)
listdisplay.grid(row=0, column=10)
root.mainloop()
Is this the sort of thing you were looking for ?
from tkinter import *
root = Tk()
root.title('Speakers List')
root.minsize(800, 600)
speakers = ['50']
spe = speakers[0]
def add():
entry=e.get()
speakers.append(entry)
listdisplay.config(text=speakers)
return
def forward():
if len(speakers) is 0:
return
else:
del speakers[0]
listdisplay.config(text=speakers)
spe=speakers[0]
n.config(text=spe)
return
entry = StringVar()
e = Entry(root, width=30, font=("Arial", 20), textvariable=entry)
e.grid(row=0, sticky=W)
s = e.get()
button1 = Button(root, padx=10, pady=10, bd=5, text='Add', fg='black',command=add)
button1.grid(row=0, column=1)
button2 = Button(root, padx=10, pady=10, bd=5, text='Next', fg='black',command=forward)
button2.grid(row=1, column=1)
n = Label(root, font=("Arial", 35), bd=2, text=spe)
n.grid(row=1, sticky=W)
listdisplay = Label(root, font=('Arial', 20), text=speakers)
listdisplay.grid(row=0, column=10)
root.mainloop()
If so:
You create a list and then you use the append function to add an item to it. The rest was pretty much right.
