Ekstrakcja danych w Pythonie. Teoria i praktyka
Piotr Rybka
Dane: załaduj, przetwarzaj, analizuj Ekstrakcja danych jest procesem, w którym informacje pozyskuje się z różnych źródeł - zwykle po to, by następnie poddać je dalszej transformacji i analizie. Umiejętność pozyskiwania danych, scalania, filtrowania i obrabiania ich na rozmaite sposoby przydaje się nie tylko zawodowym analitykom. Zdolność poruszania się po świecie danych jest wysoce pożądana również u osób pracujących w działach IT i na stanowiskach menadżerskich. Kto ma dane, ten ma wiedzę i zyskuje przewagę nad konkurencją! Jeśli chcesz zgłębić teorię ekstrakcji danych i zdobyć praktyczne umiejętności pozwalające operować nimi w Pythonie, ten podręcznik powinien być dla Ciebie pozycją obowiązkową. Dzięki książce między innymi: Opanujesz podstawowe pojęcia, których znajomość jest niezbędna podczas działań na zbiorach danych Zrozumiesz specyfikę plików binarnych i tekstowych Dowiesz się, na czym polega kodowanie tekstu Poznasz zagadnienia wyrażeń regularnych Zorientujesz się, jakie formaty wymiany danych są dostępne w Pythonie Nauczysz się przeszukiwać dokumenty znacznikowe Zapoznasz się ze schematami formatów wymiany danych
