[Message part 1 (text/plain, inline)]

Hi,

New keywords "match" and "case" were added to block-start in
`python-rx', which enables basic indentation support for these
keywords.  However, "case" does not work as a dedenter.  For example,
try the following code.

#+begin_src python
match a:
    case 1:
        print(1)
        case 2:
#+end_src

At the "case 2:" line, inputting ":" does not dedent the line.
Several TAB keys are needed for correct indentation.

Attached is a patch to make "case" a dedenter with an ERT.
