[Tkinter] Database with gui

[mark9]

Ok, writing like that:

def get_selected_row(event):
    global selected_row
    index = list.curselection()
    if not index:
        return
    selected_row = list.get(index)
    e1.delete(0,END)
    e1.insert(END,selected_row[1])

Seems working fine now. Thank you.
About the search function..what if I want that when I type more than 1 field, it must check rows matching all those field, even if some are blank.
If use ADD in backend.search(), all fields must be filled. Perhaps to do what I mean it would take a lot more lines and logical checks. I hope you understand what I mean.
And thank you again.
