Krzysztof Łos
Książka "Python dla nastolatków. Projekty graficzne z Python Turtle" Krzysztofa Łosa zdobyła wyróżnienie w kategorii podręczników w konkursie na Najlepszą Polską Książkę Informatyczną 2023r. organizowanym przez Polskie Towarzystwo Informatyczne. Każdy może zostać programistą! Czy wiesz, czym się zajmuje programista? To ktoś, kto, używając swojego umysłu i odpowiedniego języka programowania, rozwiązuje rozmaite problemy. Programista to taki współczesny superbohater. Przychodzi, siada do komputera, szybko przebiega palcami po klawiaturze i proszę ― działa. Oczywiście, to pewne uproszczenie, ale... Brzmi ciekawie? Słusznie. Bo praca programisty, kodera, developera jest ciekawa. I fajna. I daje dużo satysfakcji. A najlepsze jest to: podstaw programowania można się szybko nauczyć, po prostu się bawiąc. We własny, ulubiony sposób. Choć Twoim przewodnikiem po świecie programowania w Pythonie będzie żółw, obiecujemy ― praca pójdzie Ci w mig. Na początek nauczysz się konfigurować środowisko pracy, czyli uruchomisz na komputerze wszystko, co przyda się Tobie i żółwiowi. Potem zapoznasz się z językiem Python, z jego zmiennymi, funkcjami i klasami. Następnie zajrzysz do biblioteki turtle i dowiesz się, jak sterować swoim żółwiem. Wreszcie najlepsze: algorytmy. Przekonasz się między innymi, jak za pomocą kodu języka Python i elementów biblioteki turtle wygenerować niesamowite figury geometryczne. UWAGA! Książka jest polecana osobom biorącym udział w konkursie Logia. Informacje o konkursie można znaleźć pod adresem: logia.oeiizk.waw.pl
Python dla programistów. Big Data i AI. Studia przypadków
Paul J. Deitel, Harvey Deitel
Programiści lubią Pythona. Ujmuje ich wyrazistość, zwięzłość i interaktywność kodu, a także bogata kolekcja narzędzi i bibliotek. Zalety te są uzupełniane przez rozwój innych technologii, zwiększającą się dostępność coraz szybszego sprzętu oraz rosnącą przepustowość internetu. Z kolei to wszystko wiąże się z powstawaniem niewyobrażalnych ilości danych, które trzeba magazynować i efektywnie przetwarzać. Większość innowacji w świecie informatyki koncentruje się wokół danych. A z tymi zadaniami można sobie poradzić dzięki imponującym możliwościom Pythona i jego bibliotek. Ta książka ułatwi naukę Pythona metodą analizy i eksperymentów. Zawiera ponad 500 przykładów faktycznie wykorzystywanego kodu - od krótkich bloków po kompletne studia przypadków. Pokazano, w jaki sposób można kodować w interpreterze IPython i notatnikach Jupytera. Znalazł się tu obszerny opis Pythona oraz jego instrukcji sterujących i funkcji, omówiono pracę na plikach, kwestie serializacji w notacji JSON i obsługę wyjątków. Zaprezentowano różne paradygmaty programowania: proceduralnego, w stylu funkcyjnym i zorientowanego obiektowo. Sporo miejsca poświęcono bibliotekom: standardowej bibliotece Pythona i bibliotekom data science do realizacji złożonych zadań przy minimalnym udziale kodowania. Nie zabrakło wprowadzenia do takich zagadnień data science jak sztuczna inteligencja, symulacje, animacje czy przygotowanie danych do analizy. W książce między innymi: przetwarzanie języka naturalnego IBM stosowanie bibliotek scikit-learn i Keras big data, Hadoop(R), Spark™, NoSQL i usługi chmurowe programowanie dla internetu rzeczy (IoT) biblioteki: standardowa, NumPy, Pandas, SciPy, NLTK, YexyBlob, Tweepy, Matplotlib i inne

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary.This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.
