我该如何花时间将其发布并在不久后离开？

Question

如何发送消息？因为我想在同一位置以不同的颜色显示更多消息，并且消息都结束了，所以导致了错误。

class Users:
    def __init__(self,window):
        #Criando o sistema
        self.wind = window
        self.wind.title("System F2T")

        self.msgR = Label(text="",fg="red")
        self.msgR.place(x=110,y=110)
        self.msgR.configure(background="black")
        self.msgY = Label(text="",fg="yellow")
        self.msgY.place(x=110,y=110)
        self.msgY.configure(background="black")

    def delete (self):
        self.msgY['text'] = ''
        try:
            self.tree.item(self.tree.selection())['text'][0]
        except IndexError as e:

        self.run_query(query, (user, ))
        self.msgR['text'] = 'Usuário {} deletado com sucesso!'.format(user)
