Treeview Update Records - Python Tkinter GUI Tutorial #121

In this video I'll show you how to update the records or rows of data in your Treeview with Tkinter and Python. We've looked at creating records and deleting them, but we haven't looked at updating them yet, and it's actually pretty easy! We'll just grab the record number using the .focus() function, and then grab the current values with .item() before outputting those values to entry boxes that we can update, and then save again using the .item() function again.
