This is an example of the “traditional” use of the Scrollbar widget.  Here it is paired with Text widget inside a LabelFrame widget.  It is worth noting that there is a supporting module called “scrolledtext” that does this work for you though I have noted that Stackover frequent guru Brian Oakley feels we are better off doing it the old fashioned way.  This works great using pack but is somewhat more problematic with grid and we have not tried it with place.

#Scrollbar Test with a Text widget in a LabelFrame
#standard set up header code 2 
from tkinter import *
root = Tk()
root.attributes('-fullscreen', True)
root.configure(background='SteelBlue4')
scrW = root.winfo_screenwidth()
scrH = root.winfo_screenheight()  
workwindow = str(1024) + "x" + str(768)+ "+" +str(int((scrW-1024)/2)) + "+" +str(int((scrH-768)/2))
top1 = Toplevel(root, bg="light blue")
top1.geometry(workwindow)
top1.title("Top 1 - Workwindow")
top1.attributes("-topmost", 1)  # make sure top1 is on top to start
root.update()                   # but don't leave it locked in place
top1.attributes("-topmost", 0)  # in case you use lower or lift
#exit button - note: uses grid
b3=Button(root, text="Egress", command=root.destroy)
b3.grid(row=0,column=0,ipadx=10, ipady=10, pady=5, padx=5, sticky = W+N)

# NOTE CAREFULLY the ORDER in which the LabelFrame, Scrollbar and
# Text widget are CREATED AND PACKED - does not work any other way!

lf1=LabelFrame(top1, width=225, height=768) #create a LableFrame object -DONT pack

sbar1 = Scrollbar(lf1)    #create a scrollbar and pack in LabelFrame on right
sbar1.pack(side="right", fill="y")
                          #create a text and pack in LabelFrame on left, fill both
t1=Text(lf1, width=40, height=30, wrap=CHAR, yscrollcommand=sbar1.set)
t1.pack(side="left", fill="both", expand=True) #pack it in lf1
t1.insert(END, t1text)                      # then fill it up

sbar1.config(command=t1.yview) #now connect scrollbar and text frame

lf1.grid(row=0, column=0)  # when all that is done, grid the LabelFrame
                           # any other sequence voids propagate
lf1.pack_propagate(False)  #without propagate the text frame expands
