Basic configuration guide for Linux Python development using Eclipse

When we develop Python in a Linux environment, a powerful integrated development environment (IDE) is very helpful. Eclipse is a very popular cross-platform IDE that provides many functions and plug-ins to improve our development efficiency. This article will describe how to configure Eclipse on a Linux system for Python development, and provide some common functions and code examples.

1. Install Eclipse

First, we need to download and install Eclipse. You can download the Eclipse installation package for Linux from the Eclipse official website (https://www.eclipse.org/downloads/). Select the package that is compatible with your system and architecture and download it to your computer.

After completing the download, unzip the installation package. Navigate to the unzipped folder in the terminal and run the following command to start Eclipse:

./eclipse

2. Install Eclipse Plugin

After installing Eclipse, we need to install the applicable Plug-in developed in Python. In the Eclipse menu bar, select Help > Eclipse Marketplace.

Search for "PyDev" in the Eclipse Marketplace, and then install the plug-in. After the installation is complete, restart Eclipse.

3. Create Python Project

In Eclipse, we can easily create Python projects. Select File > New > PyDev Project to create a new project. Follow the wizard's instructions to name and configure the project.

After creating the project, we can right-click on the project and select New > PyDev Module to create a new Python module.

4. Writing and running Python code

Writing Python code in Eclipse is very easy. After creating a Python module, we can enter the code directly in the editor.

Here is an example of a simple Python program:

def hello_world():
    print("Hello, World!")
    
hello_world()

To execute the code, right-click the Python file in the editor and select Run As > Python Run. The program will print "Hello, World!" in the console window.

5. Debugging Python code

Eclipse also provides powerful debugging tools to facilitate us to find and fix errors during the development process.

To debug Python code, first set breakpoints in the code. Click in the empty space next to the line number on the left to set or cancel a breakpoint.

Then, right-click the Python file in the editor and select Debug As > Python Run. The program will run in debug mode and stop when it reaches the breakpoint. You can use Eclipse's debugging tools to view variable values, step through code, and inspect variables and expressions at runtime.

6. Import an existing Python project

If you already have an existing Python project, you can use Eclipse to import and develop it. Select File > Import to import the project. In the import dialog box, select General > Existing Projects into Workspace and select the folder containing the projects you want to import.

After importing the project, you can follow the steps mentioned before to write and run the code.

Summary

This article introduces how to configure Eclipse on a Linux system for Python development. Eclipse is a powerful IDE that provides many development tools and plug-ins that can improve our productivity. We also provide some simple code examples to help you get started with Python programming. I hope this article can help you use Eclipse for Python development on Linux.
