scripting

I'm developing a web game in pure Python, and want some simple scripting available to allow for more dynamic game content. Game content can be added live by privileged users.

It would be nice if the scripting language could be Python. However, it can't run with access to the environment the game runs on since a malicious user could wreak havoc which would be bad. Is it possible to run sandboxed Python in pure Python?

If not, are there any open source script interpreters written in pure Python that I could use? The requirements are support for variables, basic conditionals and function calls (not definitions).
