Docstrings don't automatically indent themselves in elpy-mode. How do I fix this?

Question

This is an example function that shows that docstrings do not automatically indent.

def testing_docstring():
    """
docstring is not indented automatically!
Even after a newline.
"""
    body_is_indented_though
    return

Selecting a region inside the docstring and hitting tab won't work either. Only hitting tab on a single line will toggle the indent level. How can I set docstrings to automatically indent?

Answer 1

elpy has a function elpy-open-and-indent-line-below which is binded to <S-return>.

After """, you can hit <S-return> to open new line and indent automatically. You can use this at the end of line.

Alternatively, you can bind return to this function.

(define-key elpy-mode-map (kbd "<return>") 'elpy-open-and-indent-line-below)
