This has to do with evaluation order, the stuff inside the parens gets
evaluated first, resulting in an integer for versions of python less
than v3.

You only have to give one float value:  int1/float(int2).  The
environment converts it to a floating point operation when either of
the two is a float value.  (try:  1/2.0, for example)

I agree on this one, though I prefer C's syntax of switch/case.  The
if/then/elif "ladder" of python is a bit cumbersome, but was chosen to
reduce language size -- a value with mixed reviews.

This one got answered, it has to do with the parser when dealing with parens.

No, but Python is still the best language.

Personally, I wouldn't recommend Python for web scripts.  But I'm
biased and am speaking from where I see the field of computer
languages heading.
