# Using the IPython terminal in Glue¶

Glue includes a button to open an IPython terminal window:

This gives you programmatic access to Glue data. A number of variables are available by default (these are also listed when you open the terminal):

• dc / data_collection refer to the central DataCollection, which is an object that holds all of the datasets, subsets, and data links
• hub is the main communication hub.
• application is the top level GlueApplication, which has access to plot windows (among other things)

Additionally, you can drag datasets and subsets into the terminal window, to easily assign them new variable names.

Most of your interactions will likely be with data objects and the data collection, so let’s take a look at these in the next section!
