Thank you for your reply!
Even if I don't need to install plpythonu,
RPM package includes "CONFIGURE = --with-python".
Therefore I think that I need to install python2 when RPM install.

Is my understanding correct?

If it is installing plpythonu, then yes. From the docs:
https://www.postgresql.org/docs/12/plpython-python23.html
"The language named plpythonu implements PL/Python based on the default
Python language variant, which is currently Python 2. (This default is
independent of what any local Python installations might consider to be
their “default”, for example, what /usr/bin/python might be.) The
default will probably be changed to Python 3 in a distant future release
of PostgreSQL, depending on the progress of the migration to Python 3 in
the Python community."
