Emacs bulk indent for Python

Question

Working with Python in Emacs if I want to add a try/except to a block of code, I often find that I am having to indent the whole block, line by line. In Emacs, how do you indent the whole block at once.

I am not an experienced Emacs user, but just find it is the best tool for working through ssh. I am using Emacs on the command line(Ubuntu), not as a gui, if that makes any difference.

Answer 1

I do something like this universally

;; intent whole buffer 
(defun iwb ()
  "indent whole buffer"
  (interactive)
  ;;(delete-trailing-whitespace)
  (indent-region (point-min) (point-max) nil)
  (untabify (point-min) (point-max)))
