AFAIK historical reasons.  There where some concerns about ambiguity.  But
in Python 2.5 this form will become legal syntax.

You forgot the parenthesis for the `close()` method.

In Python <=2.4 you have to nest:

try:
    try:
       pass
    except Error:
       pass
finally:
    pass

Maybe you are interested in the new (Python 2.5) ``with`` statement too:

And the style guide: http://www.python.org/dev/peps/pep-0008/ (because you
used Java naming conventions)
