How do I add a scrollbar to my tkinter frame?

Question

I am a python beginner. I spent a couple of hours trying to add a scroll bar to my tkinter frame and I can't seem to make it work. Tried many suggested solutions from the internet but all of them failed.

This is the cut down version of my codes. Could anyone help please?

from tkinter import *
from tkinter import messagebox as mb
from tkcalendar import DateEntry
import tkinter as tk
import datetime
import csv

root = tk.Tk()
root.geometry('520x900+900+85')
root.title("Location Sheet")

# Widget frame for scrollbar
widget_frame = Frame(root, bg = "#FFFFFF")
widget_frame.pack(side = "right", fill = Y)

#create a scrollbar for widget frame
scroll_widget = Scrollbar(widget_frame, orient=VERTICAL)
scroll_widget.pack(side = 'right', fill = Y)
#widget_frame.config(yscrollcommand = scroll_widget.set)
#scroll_widget.config(command = widget_frame.yview)
#scroll_widget.config(command = widget_frame.yview)

root.mainloop()
