[docs] [issue20683] Add example to tutorial namespace doc, section 9.2

[Berker Peksag]

Berker Peksag added the comment:

Thanks for the report, Karl. Could you give more details about what's missing? The section gives some examples of namespaces:

    [...] the set of built-in names (containing functions such as abs(), and built-in exception names); the global names in a module; and the local names in a function invocation.

I'm not sure if it's worth to convert them to code examples.
