[Eclipse] Integrated with Pydev

Introduction

Truth be told, I have never used eclipse for python. but it would be great to integrate all popular programming languages into one IDE.

Installation

Pydev is a plugin that enables users to use Eclipse for Python and Jython development. It distributed under the EPL license.

Before getting started, please make sure you have following software installed in your system:

• Eclipse
• Python Interpreter: Generally, python is a build-in software for Linux.

Just follow few steps, and you will never need to compile your python program in terminal.

• Start your eclipse
• Click "Help" -> "Software Updates"
• In "Available Software" section, press "Add Site" button
• add the url "http://pydev.sourceforge.net/updates/" and click "OK"
• Check and install the Pydev

Configuration

After the installation, you probably need to given a path of python interpreter in eclipse's "Preference".

• in eclipse, click "Window" -> "Preference"
• expend the "Pydev", click "Interpreter - Python"
• in "Python interpreter" section, click "New" button
• setup a location of the python interpreter.

For example, my python interpreter is located at "/usr/bin/python".


Create a python project

• in eclipse, click "File" -> "New" -> "Other"
• expand the "Pydev", click "Pydev Project"
• given a project name and click "Finish"

Create a python module

• in eclipse's Package Explorer, click your python project's "src"
• click "File" -> "New" -> "Other"
• expand the "Pydev", click "Pydev Module"

• click "Next" to continue
• given a module name and leave the template <Empty>

• click "Finish"

Coding

Below is a very trivial example to output an inverse triangular shape.

# An ugly recursive method
def star(start, end ,step, pat, pre):
if(start < end): star(start + step, end, step, pat, pre + pat)
print pre.center(end * len(pat))

height = int(raw_input("Please enter a height:"))
star(1, height, 1, "* ", "* ")
Compile and Run

Just press the "Run As" and choose the "Python Run", you will see a BEAUTIFUL pattern.

(Your output might different with mine. If you are really confused about it. You must be a ...... idiot!)

Conclusion

For the newer, Pydev could be your first choice for python programming.
