What is the equivalent of the C# “using” block in IronPython?

I'm writing some IronPython using some disposable .NET objects, and wondering whether there is a nice "pythonic" way of doing this. Currently I have a bunch of finally statements (and I suppose there should be checks for None in each of them too - or will the variable not even exist if the constructor fails?)

def Save(self):
    filename = "record.txt"
    data = "{0}:{1}".format(self.Level,self.Name)
    isf = IsolatedStorageFile.GetUserStoreForApplication()
    try:                
        isfs = IsolatedStorageFileStream(filename, FileMode.Create, isf)
        try:
            sw = StreamWriter(isfs)
            try:
                sw.Write(data)
            finally:
                sw.Dispose()
        finally:
            isfs.Dispose()
    finally:
        isf.Dispose()

Answer 1

Python 2.6 introduced the with statement, which provides for automatic clean up of objects when they leave the with statement. I don't know if the IronPython libraries support it, but it would be a natural fit.

Answer 2

I think you are looking for the with statement. More info here.
