Here you rebind 'sha' from what it was before (presumably the module sha)
to the result of 'sha.new' presumably the new 'sha' doesn't have a 'new'
method. try renameing your result variable.

            result = sha.new(f.read())
            result.update(f.read())
            print result.hexdigest()

also I don't think you need the second call to update as f will
have been read by this time and it will add nothing.
