I found nothing that helped as much as you have already.
In the reference (for 2.6.2) under print statement I find:
"print evaluates each expression in turn and writes the resulting object
to standard output (see below). If an object is not a string, it is
first converted to a string using the rules for string conversions.
This leaves the reader pondering "rules for string conversions". I
wonder whether this is defined and why it was not cross-referenced here.
I'm not sure why there's no cross-reference, or even where it should
cross-reference to, but the rules for string conversion are that:
if the object has a method __str__, it is called and the result used;
if not, but it has a method __repr__, it is called and the result used;
if not (only relevant for old-style classes in Python 2.x), then Python
has a default string format.
