In object-oriented scripting languages like Python, variables can also hold objects. In ArcMap, an object might be a map document, a feature class, or a goedatabase. I'm gonna go over to Idol and demonstrate some of the points about using variables in Python. I'll just use the shell window rather than writing an actual script. Variables can have almost any name you want, it's just something you make up. As long as you follow a few simple rules and don't use any of the reserved words in Python, like print.
