Running a Python program inside SPSS
Getting Python to combine with Syntax
This chapter is the gateway to becoming a SPSS power user. It includes the mechanics you need to know to be able to write Python programs that run inside SPSS. Integrating Python with SPSS makes possible some things that would otherwise be difficult to do in the Syntax language. To use Python, you need to know the basics of the SPSS Syntax command language because you actually reach out of Python and into the Syntax language to issue commands to SPSS. You can think of the Python plug-in as an extension of the built-in Syntax language.
Python was designed to be a general-purpose language, so it has a much larger scope than you'll ever need for SPSS programming. This large scope means that it contains features and capabilities you'll never use within SPSS. On the other hand, it also means that you can solve special problems unique to your situation.
Don't let Python's size intimidate you. It's sort of like having a pocket calculator with lots of extras — if you see a button that doesn't make sense to you, ignore it.
