Here we import tkinter GUI

from tkinter import*

Here we define a main() function
def main():
    [ create a main window]
    main_window = Tk()
    [ set title of main window ]
    main_window.title('Message: www.EasyCodeBook.com')
    [ set size of main window ]
    main_window.geometry("600x500")
    [ create a list of 5 quotes strings with index 0 to 4]
    quote_list=["A real friend is one who walks in when the rest of the world walks out.",
               "Real friends are hard to find, difficult to leave and impossible to forget.",
                "A single rose can be my garden… a single friend, my world.",
                "I don’t need a friend who changes when I change and who nods when I nod; my shadow does that much better.",
                "Be slow to fall into friendship; but when thou art in, continue firm & constant."]
    
                
    [Put first quote at index 0 in a string variable] 
    ind=0          
    str_quote = quote_list[ind]
    [ create a message widget ]
    msg = Message(main_window, text = str_quote,
                 padx=20, pady=20, bd=5, relief = GROOVE)
    [ set back ground color, foregrond color (font color)
      font name verdana, font size of message widget]
    msg.config(bg='green', fg='white', font=('verdana', 30))
    [ Place message widget in main window]
    msg.pack()
    [ define a user defined function move_quote()]
       
    def move_quote():
        [ get selected value from Spinbox, make it integer]
        ind = int(spinbox1.get())
        [ get the quote string at that selected index
          ind-1 since if value is 5 then actual index=4
           index of list is from 0 to 4 and Spinbox values 1 to 5
         ] 
        
        str_quote = quote_list[ind-1]
         
        [ put that selected quote in message widget now]
        msg.config(text=str_quote)
        
    
    [create a spinbox with values from 1 to 5
      note that parameter is from_=1 , to=5]
    spinbox1 = Spinbox(main_window, from_=1, to=5,
                       command=move_quote,font=('verdana',30),width=10)
    [Place Spinbox widget on bottom side of main window]
    spinbox1.pack(side=BOTTOM)
    [ Start the main loop, to start GUI of Python Quotes Changer
      GUI program using tkinter GUI package]
    mainloop()

[ call the main() function to start execution]
main()
