The Problem
Developers often need a minimal, reproducible example of how to package and distribute a Python library. Without a concrete reference they may misconfigure metadata, omit required files, or struggle to set up a test harness.
What This Does
mypackage is a skeletal Python package that demonstrates the standard layout for a distributable library. The source lives in mypackage/ with an init.py (exposes the package) and a single module myModule.py containing the implementation. Packaging metadata is defined in setup.py, and the generated distribution archive appears in dist/mypackage-0.1.tar.gz. The tests/ folder holds a single test module test.py that exercises the public API.
How To Use It
Setup – Install the package locally with the standard setuptools workflow:
From the repository root
pip install . or, for editable development pip install -e .
Configuration – The library does not require external configuration files or environment variables. All runtime behavior is contained in myModule.py.
Running it – Import the package in Python code and call the exposed functions. Example:
from mypackage.myModule import somefunction
result = somefunction() print(result)
If you need to rebuild the distribution archive, run:
python setup.py sdist
The resulting tarball will be placed in dist/.
Real‑World Use
A data‑science team could drop mypackage into a larger project to provide a reusable utility, such as a custom data validator. Integration would look like:
project/main.py from mypackage.myModule import validaterecord
def process(record): if not validaterecord(record): raise ValueError("Invalid record") # further processing …
The test in tests/test.py can be executed with pytest (once pytest is added) to verify that validaterecord behaves as expected.
Code Health & Issues
Med – No CI/CD pipeline – No .github/, jenkins/, or other CI configuration; automated testing is not enforced. Med – Missing LICENSE – Absence of a license file leaves redistribution rights ambiguous. Low – Minimal test coverage – Only one test file (tests/test.py) exists; many code paths remain untested. Low – No explicit entry point – setup.py does not define consolescripts, so the package cannot be invoked as a CLI without additional scaffolding. Low – Documentation limited to README – No API reference or usage examples beyond the brief README excerpt.
No obvious security flaws or runtime bugs are detectable from the current file set, but the lack of error handling in myModule.py cannot be verified without reviewing its contents.
The Bottom Line
mypackage offers a clear, minimal illustration of Python packaging fundamentals, suitable for learning or as a starting template. Its utility is limited by the absence of CI, a license, and comprehensive tests, so it is best used in controlled environments or as a base to be extended with proper development practices.
