It's not PC to call Python a scripting language. "High-level interpreted
language" is the common description.
I'm only pointing that out because I think you're mixed up about what
Python *is*, as well as what Python is *called*.

But it doesn't: ``str'' works on any type (almost). Python is strongly typed:
you can't treat a number as a string, or vice versa. I can't begin to explain
how many times it caused potentially yucky bugs into obvious ones. It
is, however, polymorphic to extremes, which is why map(str, seq) works always:
you don't need to promise what types are in seq.
Explicit is Better then Implicit is one of the Python rules of living. Python
will stay explicit, so whether you think it's silly or not, this is an
essential feature, not a quirk.
