📝 Walkthrough

Walkthrough

A test case has been replaced to validate auto-detection of Python modules matching the _py{module}.py pattern. The new test creates a temporary directory with datetime.py and _pydatetime.py, then verifies that get_lib_paths() returns both files.

Changes

Cohort / File(s) Summary
Test auto-detection for Python module pattern
scripts/update_lib/tests/test_deps.py
Replaced test case asserting behavior for a known dependency with a new test validating auto-detection of _py{module}.py pattern modules; creates temporary Lib directory and verifies get_lib_paths() returns both datetime.py and _pydatetime.py

Poem

🐰 A module hops through Lib with care,
DateTime and its twin pair,
Auto-detect, no need to guess,
Dependency patterns—nothing less!
_py friends now pass the test with flair ✨

- Around line 67-79: The new assertions and file creation in

Specifically, undo the added creation of (lib_dir / "datetime.py") and (lib_dir

get_lib_paths("datetime", ...) so test_auto_detect_py_module returns to its
