Setting Tabs in a listbox

[scratchmyhead]

I'm using Python 3.8 and using Tkinter. I'm trying to set tabs inside of a listbox. I have the following code:

for record in records:
    txt =str(record[0]) + '\t' + '\t' + '\t' + str(record[1])
    lb.insert("end", txt )

But it doesn't do tabs. Both records are up against each other when displayed in the listbox. Any help would be appreciated.

try: (python 3.6 or newer)

lb.insert("end", f"{record[0]}\t\t\t{record[1]}")

That worked. Thank you.
