delete(0, END) does not work for some reason. It does not give any error messages and the rest of the code seems fine. The delete(0, END) won't delete the 0's I get in my entry boxes from the intvar and I cant figure out why it won't work. I'm using delete in another code and it works there. Could anyone help me out?
The code i got problem with.

lucky for you I have way too much free time at the moment.
Try using:
self.a3.set("")
self.a5.set("")
maybe someone who actually knows tkinter will be able to help more.
I think you should try:
part1_entry.delete(0, 'end')
part2_entry.delete(0, 'end')

I want to print like this that widget resize automatically when i resize the screen
https://i.stack.imgur.com/iSbaJ.png
https://i.stack.imgur.com/mzv9R.png
I am working on a little finance project. When I add to my balance, the entry gets listed among themselves. But I want to "change direction", so the newest entry is always on row 3 and the others lists among themselves. The problem is I don't know how to access to the other Elements to add to their row.
It should be something like that:
I entry a amount to add to the main balance- for example 40$
It gets shown on column 0, row 3
If I add another amount it should show on row 3- for example 20$, and the 40$ should move to row 4.
It should get listed like that:
row 3: 20$ ,
row 4: 40$
and so on..
Sorry for beginner mistakes, Im new to python :)

So here's my code allows you to use 3 tools:
"Split" / "Anti-Duplicate" / "Merge"
At the moment I'm working on the "Anti-Duplicate" so it's on this Frame() where the text should be displayed.
I've already done everything, even the button to open the file explorer, but for the moment the location of the file is only displayed in the cmd.
Thank you very much!
The location of the file does not show up because you created a new frame to hold the label fichier_dir inside OpenFile_AntiDuplicate() and you did not call any layout function on the frame, so the frame will not be shown.
Better create the label fichier_dir inside Anti_Duplicate() and pass it to OpenFile_AntiDuplicate() function:
def Anti_Duplicate():
...
fichier_dir = tk.Label(mainframe, bg='#1c2028', fg='white')
fichier_dir.place(relx=0.5, y=170, anchor='n')
open_button = HoverButton(mainframe, font=("Arial", 10), text="Open File..",
background='#000000', fg='white', borderwidth=2,
activebackground='#202124', activeforeground='#1195cf',
relief='ridge', command = lambda: OpenFile_AntiDuplicate(fichier_dir))
...
And update OpenFile_AntiDuplicate(...):
def OpenFile_AntiDuplicate(fichier_dir):
global antiduplicate_file
antiduplicate_file = askopenfilename(initialdir="/",
filetypes =(("Text file", "*.txt"),("All files","*.*")),
title = "Open text file"
)
fichier_dir['text'] = antiduplicate_file
...
I made a little login screen. After I put in the credentials I want the Tkinter to be closed and open a new python file. If you execute the code below it will give me the error NameError: name ttk is not defined. In the other file I imported everything and gave it the correct name.
The file I use for the login:

super().__init__(master)
self.label_username = Label(self, text="Username")
self.label_password = Label(self, text="Password")

self.label_image = Label(root, image=self.photo)
self.label_image.image = self.photo
self.entry_username = Entry(self)
self.entry_password = Entry(self, show="*")
self.label_username.grid(row=0, sticky=E)

#The sweet spot where all goes wrong...
self.destroy()
exec(open("./BatchFrame.py").read())
else:
tm.showerror("SBSHREG", "Incorrect username")

If I change self.destroy() to root.destroy() I get the following error: _tkinter.TclError: can't invoke "label" command: application has been destroyed. In the second file the functions are not done yet because I'm still working on the file, but this shouldn't have any impact on the error.
I searched everywhere and tried a lot and I still got no clue whatsoever...
Consider initializing frames in a top level class, GUI, that handles opening of both frames where LoginFrame calls its parent's open_batch() (now lambda implemented) method. Below assumes LoginFrame.py and BatchFrame.py resides in same folder as GUI_App script.
In this way, scripts run as standalone modules on one Tk() instance.

I do not agree with the method of how you are invoking your 2nd python file.
You really dont need to use exec here.
However if you really want to you need to add import tkinter.ttk as ttk to your first page for it to work right.
Your best option is to import the 2nd file on the 1st file and invoke it by calling the class name.
so for you imports on the first page you need to add import BatchFrame.
Then call it in your code.
Replace:
exec(open("./test2.py").read())
with:
BatchFrame.BatchFrame(root)
I do see one mistake in your BatchFrame class thought.
change this:
self.label_photo = Label(root, image=self.photo)
to this:
self.label_photo = Label(master, image=self.photo)
UPDATE:
To address your issue from the comment make these changes:
1: Add this to your BatchFrame Class:
class BatchFrame(Frame):
def __init__(self, master):
super().__init__(master)
self.master = master # add this
self.master.title("SBSHREG") # and this
self.master.geometry("432x480") # and this
2: Remove this from your BatchFrame file:
root = Tk()
root.title("SBSHREG")
root.geometry("432x480")
lf = BatchFrame(root)
root.mainloop()
3: Add this to your LoginFrame class:
class LoginFrame(Frame):
def __init__(self, master):
super().__init__(master)
self.master = master # add this
4: In the LoginFrame class change this:
BatchFrame.BatchFrame(root)
to this:
BatchFrame.BatchFrame(self.master)
I recommend importing batchframe instead of executing it.
from tkinter import *
import tkinter.messagebox as tm
from tkinter import ttk as ttk
from batchframe import BatchFrame
class LoginFrame(Frame):
def __init__(self, master):
super().__init__(master)
self.master = master
self.label_username = Label(self, text="Username")
self.label_password = Label(self, text="Password")
self.photo = PhotoImage(file="icon.png")
self.label_image = Label(root, image=self.photo)
self.label_image.image = self.photo
self.entry_username = Entry(self)
self.entry_password = Entry(self, show="*")
self.label_username.grid(row=0, sticky=E)
self.label_password.grid(row=1, sticky=E)
self.label_image.grid(row=3, column=2, rowspan=2, columnspan=2, sticky=W, padx=10)
self.entry_username.grid(row=0, column=1, sticky=E)
self.entry_password.grid(row=1, column=1, sticky=E)
self.logbtn = Button(self, text="Login", command=self._login_btn_clicked)
self.logbtn.grid(columnspan=2, column=1, row=2, sticky=S+E+N+W)
self.grid()
def _login_btn_clicked(self):
username = self.entry_username.get()
password = self.entry_password.get()
if username == "123" and password == "123":
tm.showinfo("SBSHREG", "Welcome 123")
#The sweet spot where all goes wrong...
self.destroy()
# Create the instance of the BatchFrame class, passing in self.master
self.batchframe = BatchFrame(self.master)
else:
tm.showerror("SBSHREG", "Incorrect username")
Then in batchframe.py change variable reference from root to master
I am working on a program where there is a scrollable frame that will be containing a large quantity of items. But with my app it does not render all of them. Can someone possibly tell me why? And how I can fix it?

I think you're exceeding the limits of the tkinter canvas. The frame you're trying to scroll is 250,000 pixels tall. I doubt the canvas can handle that.
When I make all of your inner widgets considerably smaller your code works fine.
