I am looking for a way to fix the locations of the buttons in my app. I am new to programing and I hope you can help me. When I delete one of the items on the list than the buttons should to update their position. I mean if you delete one on the middle than the rest from the bottom will go 1 position up. Also when I am loading list from txt file than the items in my app should to be destroyed.

items = [0]

def savefile():
    with open("text.txt", "w") as f:
       f.truncate(0)

       for b in items:
            f.write(b['text'] + "\n")
    
def loadfile():
    with open("text.txt", "r") as f:
        text = f.readlines()
        for line in text:
            loaditem(line)

def loaditem(txt):
    global counter
    button_text = txt.strip()
    b = tk.Button(frame1, text = button_text,font=("Arial", 12),height=2)   
    b.place(x = 0, y = counter * 50 + 0)
    items.append(b)
    b.config(command = partial(delete_button, b))
    counter += 1

def additem(*args):
    global counter
    button_text = l1.get()
    b = tk.Button(frame1, text = button_text, font=("Arial", 12), height=2)
    b.place( x = 0, y = counter * 50 + 0)
    items.append(b)
    b.config(command = partial(delete_button, b))
    counter += 1

def delete_button(button,*args):
    global counter
    index = items.index(button)
    b = (items[index])
    b.destroy()

l1 = tk.Entry(root, width=24, font=("Arial", 12))
l1.place(height=50,x=20,y=80)

frame1= tk.Frame(root,width=300,height=600,bg="grey")
frame1.place(x=20, y=150)```
