Your #Python package needs 3 things:
✅ src/packagename directory
✅ pyproject.toml file
✅ unique package name
It does NOT need to:
❌ Solve everyone's problems
❌ Be on PyPI immediately
If your code helps you, it might help others.
Join our workshop for more: Nov 6 💛

Left side in dark green with checkmark icon titled 'Do's' lists: Create a src/packagename directory, Add a pyproject.toml instead of setup.py, Create a unique package name, Consider submitting your package to pyOpenSci for peer review. Right side in purple with X icon titled 'Don'ts' lists: Don't try to solve everyone's problems, Worry about publishing to PyPI or conda-forge immediately.
