Python. Dobre praktyki profesjonalistów

Dane Hillard

Python wydaje się językiem idealnym: ma intuicyjną składnię, jest przyjemny w używaniu, umożliwia tworzenie wydajnego, elastycznego kodu. Przy tym jest wyjątkowo wszechstronny, a stosowanie go w przeróżnych celach ułatwiają liczne biblioteki tworzone przez pasjonatów. To jednak nie zmienia faktu, że aby stać się profesjonalnym programistą Pythona, trzeba nauczyć się tworzyć kod godny profesjonalisty: działający bez błędów, czysty, czytelny i łatwy w utrzymaniu. W tym celu trzeba korzystać z branżowych standardów, które określają styl kodowania, projektowania aplikacji i prowadzenie całego procesu programowania. Należy wiedzieć, kiedy i w jaki sposób modularyzować kod, jak poprawić jakość przez zmniejszenie złożoności i stosować kilka innych, koniecznych praktyk. Ta książka okaże się szczególnie cenna dla każdego, kto zamierza profesjonalnie tworzyć kod w Pythonie. Stanowi jasny i zrozumiały zbiór zasad wytwarzania oprogramowania o najwyższej jakości, praktyk stosowanych przez zawodowych wyjadaczy projektowania i kodowania. Poza teoretycznym omówieniem poszczególnych zagadnień znalazło się tu mnóstwo przykładów i przydatnych ćwiczeń, utrwalających prezentowany materiał. Nie zabrakło krótkiego wprowadzenia do Pythona, przedstawiono też sporo informacji o strukturach danych i różnych podejściach w kontekście osiągania dobrej wydajności kodu. Pokazano, w jaki sposób zapobiegać nadmiernemu przyrostowi kodu podczas rozwijania aplikacji i jak redukować niepożądane powiązania w aplikacji. Dodatkową wartością publikacji jest bogactwo informacji o ogólnej architekturze oprogramowania, przydatnych każdemu zawodowemu programiście. W książce między innymi: podstawy projektowania w Pythonie wysokopoziomowe koncepcje rozwoju oprogramowania abstrakcje i hermetyzacja kodu różne metody testowania kodu tworzenie dużych systemów a rozszerzalność i elastyczność aplikacji Pythona praktykuj profesjonalnie!
