Printing of individually returned values when running interactively

I've just noticed (the hard way) a very unusual feature of Python's
interactive interpreter mode. If you evaluate several values on
several lines, all the values are printed! For instance:
>>> if 1:
... 1
... 2
... 3
...
1
2
3
My remark will probably look strange to seasoned Pythoneers, but I'm
really surprised by discovering this. Why would anyone want a thing
like that? Doesn't it produce loads of debug-like output when pasting
more complex things?
I guess I'm more used to Lisp interactive interpreters whose REPL is
sexp-oriented, and prints the value of the last read sexp.
(If you're curious, the case that hit me hard was when I tested
mxODBC's connection with a remote database at work. I wrote something
like:
for i in range(10000):
cur.execute('insert into test ...', i)
Needless to mention, the execute() method returns a number!)
