Eclipse is definitely not a new concept for developers. It has been widely adopted within the programming community for many years. This guide aims to walk you through the process of configuring Python in Eclipse using the PyDev extension.

Eclipse functions as an Integrated Development Environment (IDE), primarily used for Java development. However, it also supports multiple other languages such as PHP, Rust, C, and C . Although there are specific IDEs tailored for Python on Linux, many users still prefer to customize their Eclipse setup to suit Python development needs.

We’ll divide the setup into three main sections:

• Install and Configure Java on Linux
• Install Eclipse IDE on Linux
• Install PyDev Plugin for Eclipse IDE

Now let’s dive into each step.

Installing Java on Linux

Before installing Eclipse, it's essential to have Java installed since Eclipse cannot run without it. The most recent version of Eclipse requires JRE/JDK 11 or higher and a 64-bit JVM.

Installing PyDev on Eclipse

PyDev is a third-party plugin designed to bring Python support into Eclipse, offering several useful features such as:

• Linter integration (e.g., PyLint)
• Code auto-completion
• Interactive console
• Refactoring tools
• Definition navigation
• Django support
• Debugging capabilities
• Unit test integration

To use PyDev, you'll need at least Java 8 and Eclipse 4.6 (Neon). To install it, we’ll use the built-in Eclipse Update Manager.

Navigate to “Menu Bar → Help → Install New Software”.

Click on “Add” and enter the URL: http://www.pydev.org/updates. Eclipse will fetch the latest PyDev package from that address. After adding the repository, select the PyDev plugin and click “Next” as shown below.

Once the installation completes, go to “MenuBar → Window → Preferences”. You should now see PyDev listed on the left side. Expand the menu to access configuration options.

The next task is setting up the Python interpreter. Click on “Choose From List” to detect all installed versions of Python. In this example, both Python 2 and Python 3.8 are available. I’ll choose Python 3.8 as the default. Click “Apply and Close” to finalize the selection.

Let’s test the setup by creating a new project. Go to “Project Explorer → Create a Project → PyDev → PyDev Project”.

You will be prompted to enter project details like Project Name, Directory, and the preferred Python Interpreter version. Fill in the necessary fields and click “Finish”.

Create a new file with a .py extension and write your code. To execute it, right-click and select “Run As → Python Run”, or click the run button in the toolbar. Alternatively, use the shortcut “CTRL F11”.

That concludes this tutorial. You’ve successfully configured PyDev in Eclipse. There are numerous additional features offered by PyDev, so feel free to explore and provide your feedback.
