Below is a practical example demonstrating the usage of a vertical scrollbar with a Listbox in Tkinter:

from tkinter import *  

# Create main window
top = Tk()  
top.title("Tkinter Scrollbar Example")  
top.geometry("300x250")

# Create a scrollbar
sb = Scrollbar(top)  
sb.pack(side=RIGHT, fill=Y)  

# Create a listbox with scrollbar functionality
mylist = Listbox(top, yscrollcommand=sb.set)  

# Add items to the listbox
for line in range(30):  
    mylist.insert(END, "Item " + str(line))  

mylist.pack(side=LEFT, fill=BOTH, expand=True)  

# Configure scrollbar to scroll listbox
sb.config(command=mylist.yview)  

# Run the application
mainloop()  

Output:

This will create a Listbox with a vertical scrollbar, allowing users to scroll through a list of 30 items.
