If you are doing this after code has already written on the line above, you should be able to do the auot indent with the insert.
Going by the documentation you can use a column, row index for positioning.
Here is a link on stackoverflow. The first response has an example.

As a side not python3's f-string recognizes   as a space character. I found this out experimenting on something for displaying. I do not know about the tkinters text widget but, the labels will use it.
