Also, it's not clear to me why all of these internal _ prefixed internal modules are being displayed.

this is becase this line

cpython/Lib/test/test_sqlite3/__init__.py

Line 15 in a15aeec

print(f"test_sqlite3: testing with SQLite version {sqlite3.sqlite_version}")

modules will load all of the modules can load
then it load test_sqlite3 in this the verbose is 1 so will print it.

it is not because pyrepl you can run python3.12 in cpython dir
then help -> modules it will also print it

Hi all — I reproduced this locally and it matches @yihong0618’s observation. @yihong0618 are you planning to open a PR for this fix? If not, I’m happy to open one adopting your approach (with credit).

Also, it might be worth considering a focused test for help('modules') in a separate PR to prevent regressions.
