Hi!

Python would definitely throw an exception:

>>> a = {}
>>> a
{}
>>> print a['a']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'a'

And it's just as annoying as in PHP. Actually, probably more annoying
:). But it has .get() which solves the problem usually, albeit in a bit
more verbose way. Also, Python has defaultdict which I would usually use
when I need keys to be created automatically.
