ls *.pyc *.pso >> .hidden

should work

root at localhost:~# mkdir hide_test
root at localhost:~# cd hide_test/
root at localhost:~/hide_test# touch a.pyc b.pyc c.pyo d.py e.txt
root at localhost:~/hide_test# ls
a.pyc  b.pyc  c.pyo  d.py  e.txt
root at localhost:~/hide_test# ls *.pyc *.pyo >> .hidden
root at localhost:~/hide_test# cat .hidden
a.pyc
b.pyc
c.pyo
root at localhost:~/hide_test#

As this adds specific results of ls you will need to schedule the
command through cron to get it to automatically add new files
