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.

Michael Walker

Przetwarzanie dużych ilości danych daje wiedzę, która leży u podstaw istotnych decyzji podejmowanych przez organizację. Pozwala to na uzyskiwanie znakomitych efektów: techniki wydobywania wiedzy z danych stają się coraz bardziej wyrafinowane. Podstawowym warunkiem sukcesu jest uzyskanie odpowiedniej jakości danych. Wykorzystanie niespójnych i niepełnych informacji prowadzi do podejmowania błędnych decyzji. Konsekwencją mogą być straty finansowe, stwarzanie konkretnych zagrożeń czy uszczerbek na wizerunku. A zatem oczyszczanie jest wyjątkowo ważną częścią analizy danych. Ta książka jest praktycznym zbiorem gotowych do użycia receptur, podanych tak, aby maksymalnie ułatwić proces przygotowania danych do analizy. Omówiono tu takie kwestie dotyczące danych jak importowanie, ocena ich jakości, uzupełnianie braków, porządkowanie i agregacja, a także przekształcanie. Poza zwięzłym omówieniem tych zadań zaprezentowano najskuteczniejsze techniki ich wykonywania za pomocą różnych narzędzi: Pandas, NumPy, Matplotlib czy SciPy. W ramach każdej receptury wyjaśniono skutki podjętych działań. Cennym uzupełnieniem jest zestaw funkcji i klas zdefiniowanych przez użytkownika, które służą do automatyzacji oczyszczania danych. Umożliwiają one też dostrojenie procesu do konkretnych potrzeb. W książce znajdziesz receptury, dzięki którym: wczytasz i przeanalizujesz dane z różnych źródeł uporządkujesz dane, poprawisz ich błędy i uzupełnisz braki efektywnie skorzystasz z bibliotek Pythona zastosujesz wizualizacje do analizy danych napiszesz własne funkcje i klasy do automatyzacji procesu oczyszczania danych Prawdziwą wartość mają tylko oczyszczone i spójne dane!
