The above is manually created, because CMD doc operation is not very convenient, and add my Java background, accustomed to eclipse, so the following way to create the project is to use the Eclipse+python plug-in to create;

1. Download eclipse:http://www.eclipse.org/downloads/

2. Download Python plugin: PyDev

Move all files under the plugins directory to the corresponding directory in Eclipse, move all files under the feature directory to the corresponding directory in Eclipse, and finally launch Eclipse, Software upates-in help-"Manage" Configuration and then pops up the interface to see the Pydev plugin.

Before installing PyDev, make sure that you have installed Java 1.4 or later, Eclipse, and Python. Next, start installing the PyDev plugin. Start Eclipse and install PyDev with Eclipse Update Manager. Locate the Help bar in the Eclipse menu bar and select Help > Software Updates > Find and Install. Select Search for new features for install, and then click Next. In the displayed window, select New remote site. A dialog box pops up asking for the name and link of the new update site. Here, the name entry PyDev, of course, you can also enter a different name, the link input http://pydev.org/updates. Then, click Ok.

3. Configure the Python path:

After installing the PyDev, you need to configure the Python/jython interpreter, which is simple to configure.

In the Eclipse menu bar, select Window > Preferences > Pydev > Interpreter-(Python/jython), where you configure the Python/jython interpreter, following the Python Provides an example of how to configure.
