Get your package started by converting scripts you have already written. You'll create a simple package which you can use on your own computer.

Starting a package

Modules, packages and subpackages

From script to package

Putting your package to work

Documentation

Writing function documentation with pyment

Writing function documentation with pyment II

Package and module documentation

Importing from parents

Exposing functions to users

From Loose Code to Local Package

Make your package installable for yourself and others. In this chapter, you'll learn to deal with dependencies,  write READMEs, and include licenses. You'll also complete all the steps to publish your package on PyPI—the main home of Python packages.

Wrap-up

Rapid Package Development

Apakah Anda sering menyalin dan menempelkan kode yang sama antar berkas, dan berharap lebih mudah untuk digunakan kembali serta dibagikan? Membungkus kode Anda ke dalam paket Python dapat membantu! Di kursus ini, Anda akan mempelajari struktur paket dan berkas tambahan yang diperlukan untuk mengubah kode lepas menjadi paket yang mudah digunakan. Anda juga akan mempelajari struktur import, dokumentasi, dan cara menjaga gaya kode menggunakan flake8. Selanjutnya, Anda akan mempercepat pengembangan paket dengan membangun templat, menggunakan cookiecutter untuk membuat kerangka paket. Terakhir, Anda akan belajar cara menggunakan setuptools dan twine untuk membangun dan menerbitkan paket Anda ke PyPI—panggung dunia bagi paket Python.
