How to insert scrollbar in a specific position in Tkinter?

Hi guys i'm having trouble with a scrollbar, in the photo you can see the grey box that is a simple listbox, how to put the scrollbar in that red specific position, and not in the right or bottom end of the screen just like te normal scollbar? Thanks!
adding code:
from tkinter import *

scrollbar = Scrollbar(frame,command=lista_spese.yview)
scrollbar.pack(side=RIGHT,fill=Y)
lista_spese.config(yscrollcommand=scrollbar.set)
window.mainloop()

Simply put both (Listbox and Scrollbar) in the same Frame to group them.
Minimal working code
import tkinter as tk
root = tk.Tk()
root['bg'] = '#ff8080'
# - create -
frame = tk.Frame(root)
frame.pack(padx=150, pady=150)
listbox = tk.Listbox(frame)
listbox.pack(side='left', fill='both', expand=True)
scrollbar = tk.Scrollbar(frame, orient='vertical', command=listbox.yview)
scrollbar.pack(side='right', fill='y')
#scrollbar.pack(side='left', fill='y') # `left` also works
listbox.config(yscrollcommand=scrollbar.set)
# - add some values to listbox for scrolling -
for i in range(50):
listbox.insert('end', str(i))

You may also use Frame to create own widget ScrolledListbox and then you can reuse it many times.

Adding a header line to a scrollable canvas with weights

I'm trying get a list of .xlsm files from a folder, and generate a scrollable canvas from which the tabs needed for import can be selected manually using the check buttons (all having the same tab format e.g. tab1, tab2, tab3, tab4).
The major issue I'm having is getting weights to work correctly for the headers in relation to their canvas columns, as longer file names distorts the weight.
I've tried playing with the weights and can't seem to figure out a workaround. I also attempted using treeview as an alternative but this seems to introduce far bigger issues with using checkbuttons. Would it possible to freeze the top row if the headers were placed inside the canvas itself, or could I implement something like a bind so that the header frames individual columns align with the width of the columns of the canvas frame?

The simplest solution is to use two canvases, and then set up a binding so that whenever the size of the inner frame changes, you update the headers to match the columns.
It might look something like this:
def config_frame(self, event):
self.canvas.configure(scrollregion=self.canvas.bbox('all'), yscrollcommand=self.scroll_y.set)
self.canvas.after_idle(self.reset_headers)
def reset_headers(self):
for column in range(self.canvas_sub_frame.grid_size()[0]):
bbox = self.canvas_sub_frame.grid_bbox(column, 0)
self.canvas_frame.columnconfigure(column, minsize = bbox[2])

How do I create a scrollbar when using a grid in tkinter?

I'm a little bit stuck on this problem regarding my program. I tried adding as many comments as possible to give a sense of what everything does in the code, but essentially. The program has a field and value entry box. When the "add field/value button" is clicked, more of the entry widgets are added. If this keeps occurring then obviously it'll go off screen. So I've limited the size of the application, but the problem then is I need a scrollbar. I've tried looking it up, but my frame uses grid, and everywhere they use pack which isn't compatible in this case. I get the scrollbar to appear, however it doesn't seem to work. I've seen some people use canvas, and more than one frame, etc. I'm missing something important but I don't know how do the exact same thing with a grid. Think you experts can lend me hand to get it working?

You could create a Canvas and insert your Entry objects into a Frame.
Here is a simplified example that creates a 2D bank of Buttons using the canvas.create_window.
import tkinter as tk
root = tk.Tk()
# essential to enable full window resizing
root.rowconfigure(0, weight = 1)
root.columnconfigure(0, weight = 1)
# scrollregion is also essential when using scrollbars
canvas = tk.Canvas(
root, scrollregion = "0 0 2000 1000", width = 400, height = 400)
canvas.grid(row = 0, column = 0, sticky = tk.NSEW)
scroll = tk.Scrollbar(root, orient = tk.VERTICAL, command = canvas.yview)
scroll.grid(row = 0, column = 1, sticky = tk.NS)
canvas.config(yscrollcommand = scroll.set)
# I've used a labelframe instead of frame so button are neatly collected and named
frame = tk.LabelFrame(root, labelanchor = tk.N, text = "Buttonpad")
# Note I've placed buttons in frame
for fila in range(20):
for col in range(5):
btn = tk.Button(frame, text = f"{fila}-{col}")
btn.grid(row = fila, column = col, sticky = tk.NSEW)
# Frame is now inserted into canvas via create_window method
item = canvas.create_window(( 2, 2 ), anchor = tk.NW, window = frame )
root.mainloop()

Indeterminate Progress bar while function is running

I have a GUI which has two buttons and a progressbar stacked on a single column. Each button calls a different function which takes some time to execute. I want the progress bar to move when someone clicks any of the two buttons and keep moving (indeterminately) until the function finishes and then stop. I know I need to use multi-threading but I can't seem to get the code right!
Code
from tkinter import Tk
import time
from tkinter import *
from tkinter import Button
from tkinter import Frame
from tkinter import ttk
import threading
def sample_function():
time.sleep(2) # SAMPLE FUNCTION BEING CALLED
def prepare_clicked():
sample_function()
def social_clicked():
sample_function()
def anomaly_clicked():
sample_function()
window = Toplevel() # Tried using Tk but I am using image to design each buttons through the button config in my actual code and tk throws error
topFrame = Frame(window)
topFrame.pack()
prepare_btn = Button(topFrame, command=prepare_clicked,text='Button1')
anomaly_btn = Button(topFrame,command=anomaly_clicked,text='Button2')
social_btn = Button(topFrame, command=social_clicked,text='Button3')
processing_bar = ttk.Progressbar(topFrame, orient='horizontal', mode='indeterminate')
window.rowconfigure((0,1), weight=1) # make buttons stretch when
window.columnconfigure((0,3), weight=1) # when window is resized
prepare_btn.grid(row=0, column=1, columnspan=1, sticky='EWNS')
anomaly_btn.grid(row=1, column=1, columnspan=1, sticky='EWNS')
social_btn.grid(row=2, column=1, columnspan=1, sticky='EWNS')
processing_bar.grid(row=3, column=1, columnspan=1, sticky='EWNS')
window.mainloop()

I've added threading to your code. I assume you don't want any of the buttons to be pressable while a function is in progress. If you don't need that, just get rid of the for loops in run_function that change btn['state']. I've also fixed the row & column configuration code so that the widgets expand & contract when the user resizes the window. And I got rid of the evil "star" import.

func()
processing_bar.stop()
print(name, 'stopped')
# Enable all buttons
for btn in buttons:
btn['state'] = 'normal'
def run_thread(name, func):
Thread(target=run_function, args=(name, func)).start()
def prepare_clicked():
run_thread('prepare', sample_function)
def social_clicked():
run_thread('social', sample_function)
def anomaly_clicked():
run_thread('anomaly', sample_function)
window = tk.Tk()
#window = tk.Toplevel()
topFrame = tk.Frame(window)
# Tell the Frame to fill the whole window
topFrame.pack(fill=tk.BOTH, expand=1)
# Make the Frame grid contents expand & contract with the window
topFrame.columnconfigure(0, weight=1)
for i in range(4):
topFrame.rowconfigure(i, weight=1)
prepare_btn = tk.Button(topFrame, command=prepare_clicked, text='Button1')
anomaly_btn = tk.Button(topFrame,command=anomaly_clicked, text='Button2')
social_btn = tk.Button(topFrame, command=social_clicked, text='Button3')
buttons = [prepare_btn, anomaly_btn, social_btn]
processing_bar = ttk.Progressbar(topFrame, orient='horizontal', mode='indeterminate')
prepare_btn.grid(row=0, column=0, columnspan=1, sticky='EWNS')
anomaly_btn.grid(row=1, column=0, columnspan=1, sticky='EWNS')
social_btn.grid(row=2, column=0, columnspan=1, sticky='EWNS')
processing_bar.grid(row=3, column=0, columnspan=1, sticky='EWNS')

Tkinter: right align Labels within stretched LabelFrames using grid

Using grid in tkinter, I'm trying to align a set of frames (I would love to post a picture, but I'm not allowed.)
I've two outer LabelFrames of different sizes and on top of each other which I'd like to stretch and align.
Within the bottom frame, I've a stack of several other LabelFrames and within each of the LabelFrames there is a Label. I would like for the LabelFrames to extend as much as the outer container and for each of the inner Labels to be right align with respect to the containing LabelFrame.
I've tried, without success, with various combinations of sticky, anchor, justify.
Any suggestion, recommendation?

Without even running your code I see two problems. The first is that you aren't always using the sticky parameter when calling grid. That could be part of the problem. I've rarely ever used grid without using that parameter.
The second problem is that you aren't giving any of your rows and columns any weight. Without a positive weight, columns and rows will only ever use up exactly as much space as they need for their contents, and no more. Any extra space goes unallocated.
A good rule of thumb is that in every widget that is being used as a container for other widgets (typically, frames), you should always give at least one row and one column a positive weight.
As a final suggestion: during development it's really helpful to give each of your frames a distinctive color. This really helps to visualize how the frames are using the available space.

Thanks to Bryan's comment on weight, here is a working version of the code as potential reference. (I'll add pictures when allowed.)
