How to clear an entire Treeview with Tkinter

Question

My program uses a ttk.Treeview as a table and fills it with many numbers.

I want to clear the ttk.Treeview when I press a button in the window.

Is there a simple way to clear the ttk.Treeview?

Thanks.

Ok, I found. I post the answer if someone need an answer to my question :

for i in tree.get_children():
    tree.delete(i)

Answer 2

Even simpler:

tree.delete(*tree.get_children())

Following on from Katze’s answer, after you delete the tree you might need to update the window to reflect the changes

for i in tree.get_children():
   tree.delete(i)
window.update()

You’d have to keep your program in a while true loop instead of a mainloop

while True:
  if condition_check():
      for i in tree.get_children():
         tree.delete(i)
      window.update()
