In ruby all objects can be frozen (freeze is a method on Object, from
which all other objects derive), not just Arrays (Arrays == lists in

Steven,
As suggested in the previous article, I handled it where the values are
read from the list retrie
George Sakkis, I agree with the things you say.
Sometimes you may have a sequence of uniform data with unknown len (so
its index doesn't have semantic meaning). You may want to use it as
dict key, so you probably use a tuple meant as just an immutable list.
I don't know Ruby, but I think it allows

Explain. I know tuples as immutable lists

For clarity, these sequences of records should be lists (with each
item being a tuple containing the record fields), not tuples.
A tuple implies a meaning associated with each position in the
sequence

You refer to the second item as "a tuple" later, but it's not; it's

I'm a bit embarrassed to have to ask for help on this, but I'm not finding
the solution in the docs I have here.
Data are assembled for writing to a database table. A representative tuple
looks like this:
('eco', "(u'Roads',)", 0.073969887301348305)
