Rapid Package Development

Aynı kodu dosyalar arasında kopyalayıp yapıştırırken, keşke bu harika parçacıkları yeniden kullanmak ve paylaşmak daha kolay olsa diye düşünüyor musun? Kodunu Python paketlerine sarmak yardımcı olabilir! Bu kursta, dağınık kodu kullanışlı paketlere dönüştürmek için paket yapısını ve gereken ek dosyaları öğreneceksin. Ayrıca içe aktarma yapısı, dokümantasyon ve flake8 ile kod stilini nasıl koruyacağını da göreceksin. Ardından, şablonlar oluşturarak ve cookiecutter kullanarak paket iskeletleri yaratarak geliştirme hızını artıracaksın. Son olarak, paketlerini PyPI’ye—Python paketlerinin dünya sahnesine—yapılandırmak ve yayımlamak için setuptools ve twine kullanmayı öğreneceksin.
