Eclipse ide python linux

1. Overview

Eclipse is a platform that has been designed from the ground up for building integrated web and application development tooling. By design, the platform does not provide a great deal of end user functionality by itself. The value of the platform is what it encourages: rapid development of integrated features based on a plug-in model.

Eclipse provides a common user interface (UI) model for working with tools. It is designed to run on multiple operating systems while providing robust integration with each underlying OS. Plug-ins can program to the Eclipse portable APIs and run unchanged on any of the supported operating systems.

At the core of Eclipse is an architecture for dynamic discovery, loading, and running of plug-ins. The platform handles the logistics of finding and running the right code. The platform UI provides a standard user navigation model. Each plug-in can then focus on doing a small number of tasks well. What kinds of tasks? Defining, testing, animating, publishing, compiling, debugging, diagramming. the only limit is your imagination.

1.2 What is Python?

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

Often, programmers fall in love with Python because of the increased productivity it provides. Since there is no compilation step, the edit-test-debug cycle is incredibly fast. Debugging Python programs is easy: a bug or bad input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception. When the program doesn’t catch the exception, the interpreter prints a stack trace. A source level debugger allows inspection of local and global variables, evaluation of arbitrary expressions, setting breakpoints, stepping through the code a line at a time, and so on. The debugger is written in Python itself, testifying to Python’s introspective power. On the other hand, often the quickest way to debug a program is to add a few print statements to the source: the fast edit-test-debug cycle makes this simple approach very effective.

Как настроить PyDev для Eclipse IDE в Linux

Eclipse — не новый термин, который услышат программисты. Он очень популярен в сообществе разработчиков и существует на рынке уже очень давно. В этой статье показано, как настроить Python в Eclipse с помощью пакета PyDev.

Eclipse — это интегрированная среда разработки (IDE), используемая для разработки Java. Помимо Java, он также поддерживает другие языки, такие как PHP, Rust, C, C++ и т. д. Хотя на рынке есть специализированные Linux IDE для python, я все еще видел, как люди настраивали свою среду Eclipse, чтобы сделать он идеально подходит для разработки Python.

Разобьем установку на 3 части.

• Установите Eclipse IDE в Linux
• Установите PyDev поверх Eclipse IDE

Давайте сразу же посмотрим, как мы можем это настроить.

Установка Java в Linux

eclipse не запустится, пока мы не установим Java, так что это обязательный шаг. Для последней версии Eclipse требуется Java JRE/JDK 11 или выше, а также 64-разрядная JVM.

Установка PyDev в Linux

PyDev – это сторонний подключаемый модуль, созданный для интеграции с Eclipse для разработки на Python, который обладает множеством функций, включая

• Интеграция с Линтером (PyLint).
• Автозаполнение.
• Интерактивный терминал.
• Поддержка рефакторинга.
• Перейти к определению.
• Поддержка Джанго.
• Поддержка отладчика.
• Интеграция с модульным тестом.

PyDev требует Java 8 и Eclipse 4.6 (Neon) для поддержки Python 2.6. и выше. Для установки PyDev мы будем использовать менеджер обновлений Eclipse.

Перейдите в \Панель меню → Справка → Установить новое программное обеспечение».

У вас откроется окно, как показано на изображении ниже. Нажмите \Добавить и введите URL-адрес \http://www.pydev.org/updates . Eclipse позаботится об установке последней версии PyDev с предоставленного URL-адреса. Выберите пакет PyDev и нажмите и \Далее, как показано на рисунке.

После завершения установки перейдите в \Панель меню → Окно → Настройки». С левой стороны вы найдете PyDev. Разверните его. Здесь вы можете настроить среду PyDev.

Следующим шагом будет настройка интерпретатора Python. Нажмите \Выбрать из списка, как показано на изображении. Это проверит все установленные версии Python на ваших компьютерах. В моем случае у меня есть Python2 и >Python3.8 установлен. Я выберу Python 3.8 в качестве интерпретатора по умолчанию. Нажмите \Применить и закрыть, и вы успешно настроили интерпретатор Python. .

Пришло время запустить код. Создайте новый проект, выбрав \Проводник проектов → Создать проект → PyDev → Проект PyDev».

Он попросит настроить информацию, связанную с проектом, такую как Имя проекта, Каталог, версию Python Interpreter. После настройки этих параметров нажмите \Готово.

Создайте новый файл с расширением .py и поместите свой код. Чтобы запустить программу, щелкните правой кнопкой мыши и выберите \Запуск от имени → Запуск Python или нажмите значок запуска в области меню. Вы также можете нажать \CTRL+F11 для запуска программы.

Это все для этой статьи. Мы увидели, как настроить PyDev в Eclipse. PyDev предлагает гораздо больше функций. Играет с ним и поделиться своими отзывами.

Python Eclipse and PyDev Installation

Eclipse is a framework for interactive development that is being used in software development. It comprises a base platform and an optimized environment customization plug-in framework. On the other hand, PyDev is a third-party module or plug-in, which is used in Eclipse. It is an optimized development platform that facilitates code refactoring, graphic debug, code inspection, and other functions for Python coding. If you are searching for a guide to install and configure both the tools, then you are in the right place.
