Personally, I'm quite okay with automatic upcasts to string. But if
you want to be explicit, particularly with floats, the solution often
is not to use str(), but a proper number-formatting routine. You want
"String%f"%1.75 for full power.

But when you're just letting the language do the translation, it's
much of a muchness whether you put an explicit toString() call in.
