For example, there is code:

def tk_sleep():n    status_send = Tk()n    status_send.geometry('400x340')n    tx_1 = Text(status_send, font=('times', 12), width=62, height=15, wrap=WORD)n    tx_1.pack()n    for i in range(10):n        tx_1.insert(1.0, 
                        

                            
                            
                                0
