Czysty kod w Pythonie. Twórz wydajny i łatwy w utrzymaniu kod. Wydanie II

Mariano Anaya

Popularność Pythona, ulubionego języka programistów i naukowców, stale rośnie. Jest on bowiem łatwy do nauczenia się: nawet początkujący programista może napisać działający kod. W efekcie, mimo że Python pozwala na pisanie kodu przejrzystego i prostego w konserwacji, zdarzają się przypadki kodu źle zorganizowanego, nieczytelnego i praktycznie nietestowalnego. Jedną z przyczyn tego stanu rzeczy jest tendencja niektórych programistów do pisania kodu bez czytelnej struktury. Zidentyfikowanie takich problemów i ich rozwiązywanie nie jest łatwym zadaniem. Dzięki tej książce nauczysz się korzystać z kilku narzędzi służących do zarządzania projektami napisanymi w Pythonie. Dowiesz się, czym się charakteryzuje czysty kod i jakie techniki umożliwiają tworzenie czytelnego i wydajnego kodu. Przekonasz się, że do tego celu wystarczą standardowa biblioteka Pythona i zestaw najlepszych praktyk programistycznych. Opisano tu szczegóły programowania obiektowego w Pythonie wraz z zastosowaniem deskryptorów i generatorów. Zaprezentowano również zasady testowania oprogramowania i sposoby rozwiązywania problemów poprzez implementację wzorców projektowych w kodzie. Pokazano też, jak można podzielić monolityczną aplikację na mikrousługi, by otrzymać solidną architekturę aplikacji. W książce między innymi: konfiguracja wydajnego środowiska programistycznego tworzenie zaawansowanych projektów obiektowych techniki eliminacji zdublowanego kodu i tworzenie rozbudowanych abstrakcji zastosowanie dekoratorów i deskryptorów skuteczna refaktoryzacja kodu budowa solidnej architektury opartej na czystym kodzie Pythona Czysty kod w Pythonie. Tylko taki warto pisać!
