How do you insert a tab in a specific place in a tkinter ttk notebook?

I would like to know how you would set a tkinter notebook tab in a specific place. For example, I have this tab that allows you to clone other tabs, but I want it to stay at the end. The code I tried does not seem to work though, as it generates an tkinter.TclError : "Slave index (whatever number) out of bounds".

`

from tkinter import *\
from tkinter import ttk, messagebox as msg\
from widgets.translate import Translator\
from widgets.explore import FileExplorer\

root = Tk()\
root.title('Widgets')

tabs = ttk.Notebook(root, width=900, height=350)
tabs.pack(fill='both', expand=1, pady=(5, 0))

tr = ttk.Frame(tabs)
tr_frame = ttk.Frame(tr)
tr_frame.pack(fill=Y)
tabs.add(tr, text='Translator')
    
Translator(tr_frame)

explorers=0
translators=0

def fileexplore_tab(index=2):
    global explorers

    fl_explore = ttk.Frame(tabs)
    tabs.insert(index, fl_explore, text='File Explorer')
    FileExplorer(fl_explore)
    explorers += 1

fileexplore_tab(2)
fileexplore_tab(len(tabs.tabs())-1)

print(len(tabs.tabs()))

root.mainloop()

How do you insert a tab in a specific place in a tkinter ttk notebook?

The insert method allows you to specify an integer id. For example, the following code creates four tabs, then inserts a fifth in the middle.

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
notebook = ttk.Notebook(root)
notebook.pack(fill="both", expand=True)

for color in ("red", "orange", "green", "blue"):
    frame = tk.Frame(notebook, background=color)
    notebook.add(frame, text=color)

extra_frame = tk.Frame(notebook, background="white")
notebook.insert(2, extra_frame, text="white")

root.mainloop()

The first argument to insert is a numerical index. Tabs are numbered starting with zero, so the position 0 will insert the tab as the first tab. You can use the string "end" to insert the tab at the end.

last_frame = tk.Frame(notebook, background="black")
notebook.insert("end", last_frame, text="black")

The index must not be greater than the number of tabs.

Instead of a number, you can also specify a specific tab. For example, given the last_frame example from above, a tab can be inserted immediately before it by using last_frame instead of the integer position.

new_frame = tk.Frame(notebook, background='bisque')
notebook.insert(last_frame, new_frame, text="bisque")
