tkinter interface need helf : i'm developing a graphical interface with tkinter , when i open file and send it , i want to see the scrolling instructions in label (Commande) 

To be more precise i do not know how to link this instruction (print ('Sending: ' + l))  with this instruction  ( Label(Frame1, text="Commande",background='NavajoWhite2').pack(padx=165, pady=10))


Thanks to all
