What would be the best way to keep the region active after a command?
What I'm willing to do is to keep the region active after
python-indent-shift-left and python-indent-shift-right are called.
Regards,

The region is deactivated if `deactivate-mark' is non-nil at the end of
the command and this variable is set by buffer-modifying functions, so
let-binding deactivate-mark around those functions (or around the whole
command's body) is usually the way to do it.

Wouldn't it be good to have a general command like
dont-deactivate-mark-after-next-command?

No. Having a function that just sets a variable to nil is silly.

Because the user may as well just write (setq foo nil)...
If "foo" were obscure/weird, then maybe a set-to-nil function with a
clearer name could be useful useful, but in this case the variable's
meaning is quite clear.

Er, by "user" I mean the command.
