### Defining symbolic functions in Sage and importing from Maxima

Still following this thread, I would like to know how to
1. import in Sage a function defined in Maxima?
In my context, I'm interested in Maxima's pdf_normal so I started to

```
maxima("load(distrib)")
```

but how do I proceed from there?

- What is the equivalent of Maxima's := symbolic function definition?
