#1° botão
botao = Button(janela, text="Buscar poemas",command=lambda: botao_Click("Nova msg"))
botao.grid(column=0, row=1, padx=10, pady=10)

#2° botão
botao = Button(janela, text="Buscar poetas",command=lambda: botao_Click("outra msg"))

Do you want to show it inside a new Label widget or update the contents of your texto widget? — TheLizzard

Change the

  def botao_Click(mensagem):
    print(mensagem)

to def onClick(): tkinter.messagebox.showinfo("Title goes here","Message goes here")

And the button to

button = tkinter.Button(root,text = "Click Me", command = onClick)

The key is that the print method is to print to the console. tkinter.messagebox.showinfo("","") is for the popup message

Why did you rename the function? Why did you assume that OP wants to show the message in a new window? Also OP wants to be able to reuse the function to display different texts based on the button that is clicked.
