Tkinter == Label / Msg only have 1 item in the list.How to solve?

Well, the goal is to have all the items in the list in the same label or msg appear. I'm not very experienced at Tkinter, so I do not know if there's a limit to that. Here is some of the code below.

prod=['Exemplo-10.00','Exemplo2-20.00','Exemplo3-30.00']
##
def create_window():
    top = tk.Toplevel()
    top.title('Tabela de Preços')
    h=Message(top, width=310 , text='' )
    h.place(x=50,y=50)
    h.config(font=('Courier', 20))
    h.pack()
    def listagem():
        for i in prod:
            yo=int(i.find('-'))
            h['text']=str(i[0:yo]+'.......'+str(i[yo:-1]))
    bto=Button(top, width=22 , height=2 ,text='Clique para mostrar a tabela', command=listagem)
    bto.place(x=0,y=5)
    bto.pack()
    top.geometry('400x600+300+60')
