I. background

Eclipse is a Java-based scalable development platform. Its official downloads include J2EE, Java, C/C ++, and mobile application versions. In addition, Eclipse can also develop languages such as Python, Android, and PHP by installing plug-ins.

Eclipse + PyDev plug-in is the most popular Python development environment. This article will introduce the use of Eclipse and PyDev plug-ins.

Ii. Python Installation

Python installation involves three steps: Downloading python, configuring environment variables, and testing the installation.

(1) download python: It is difficult to download python on a foreign server when the network speed is poor. You can directly search for Python installation in Baidu. There is a python installation package of the latest version provided by Baidu software. Download and select the installation directory and click next.

(2) Configure environment variables: I personally feel that creating environment variables in Win8 is very good.

(3) the installation is successful. Command: python-V (V is an uppercase V)

Iii. Install the plug-in PyDev

The plugin PyDev can be installed online or offline. (The premise is that the local machine has installed Eclipse correctly)

(1) install the SDK online at: http://pydev.sourceforge.net/updates. Select PyDev for Eclipse to Finish installation. Restart Eclipse and point to the Python installed on the local machine in Window> preference> PyDev> Interpreter> Python Interpreter (translator.

(2) offline Installation

Iv. Test Demo

You can use a simple crawler instance to check whether the environment is OK.
