For example, I want to find $hello$ that does not occur at the

The begging of the string is zero width character. So you could use

You can use slightly different approach. With double mapping you could

Hi all,

Right. d.items is a dict method. d['items'] is whatever you assign.
Named tuples in the collections modules, which allow access to fields

I am not a Python developer, but Pythonic way of definition not
