Currently there is no official release of the python plugin for NetBeans 7 but support can be enabled by adding the Developer Plugin listings to your NetBeans 7 install.
To do this:
- Start NetBeans 7
- Click on Tools > Plugins
- When the Plugins window opens click the Settings Tab
- In the Settings tab click the Add button
- Type whatever Name you want for this, I used 'Developer Updates'
- Under URL put http://deadlock.netbeans.org/hudson/job/nbms-and-javadoc/lastStableBuild/artifact/nbbuild/nbms/updates.xml.gz and click OK
- The plugin list should refersh and may take a moment, when it does click on the 'Available Plugins' tab.
- In the search box there type 'python' to find the python plugin, check the box for that plugin and click Install.
Follow any other directions it gives to you but you should be up and ready to start coding in python.
