Same suffix?  How can .sh ever be the same as .py?  Oh, you meant same prefix.

Try this.  It finds all *.py files and prints them, and for all .sh files,
it forks a shell that tests whether a corresponding *.py file exists in
order to decide whether to print.

find -name '*.py' -print -o -name '*.sh' \
  -exec sh -c 'test ! -f "${1%.sh}.py"' sh {} \; -print
