Use the variable (name) in an expression.  But this is not what you ask 
below.

I think most of us have seen examples like this in programming books.

Because it is just one identifier, and you rebind it to multiple values.

starters = dinner['Starters']
main_course = dinner['Main Course']
desert = dinner['Desert']
