In Perl, I can do this:

push(@{$h->[x]}, y);

Can I simplify the following python codes according to above Perl example?

if x not in h:
  h[x] = []
h[x].append(y)

I want to simplify this, because it goes many places in my code, (and I cannot initialize all possible x with []). I do not want to make it a function, because there is no 'inline' keyword.

Any ideas?
