How to make emacs automatically indent Python code?

Question

I'm using emacs 24.3 and Ubuntu 12.04 LTS. How do I make emacs automatically indent lines in Python, like in IDLE? Currently, it does not do that.

Also, in general, how would I do this for any programming language, say, Java or c++?

Answer 1

Try electric-indent-mode . It will be ebabled by default in Emacs-24.4. But note that the version in 24.3 probably doesn't work too well in python-mode buffers.

Answer 2

You can try other python modes, like emacs-for-python or elpy, as given by this doc: http://wikemacs.org/index.php/Python (though the default mode works fine for me on the same config).

You can install them with package.el ( Mx package-install RET elpy RET ) and call them as explained.

Answer 3

用Cj打开换行符，你应该得到缩进。
