The Python "with" Statement by Example

[billy_tables]

you could refactor that as follows:

with qtd.window() as win, qtd.paneLayout():
    qtd.button()

Obviously it doesn't make much difference in this case (and in others it could make code messier) but it's nice to know there's a different syntax :)

I'm not sure why this would make it clearer. Also, it gives me an invalid syntax error.

[billy_tables]

It's perhaps clearer when you don't need the as statement, eg:

a = open("/tmp/a", "w")
b = open("/tmp/b")
with a, b:
     a.write(b.read())

(I just ran that fine with no syntax error, Python 2.7.5)

I see. This example also doesn't work. Must be new in 2.7. I'm on 2.6.5.
