Yes. Python doesn't have an "array" type natively, and it's confusing
to refer to a dict as an array because there *are* "array"s in PyNum.

Your function never specifies where 'v' comes from. So, when you first
attempt to access an item from 'v' as an existing dict, you get a
NameError.
If you want to create 'v' inside the function, you'll need to do so
before attempting to use it.
def foo():
bar = {"spam": 1}
return bar
cheeseburger = foo()
print cheeseburger["spam"]
To get a thorough grounding in basic concepts like this, please work
through the Python tutorial <URL:http://docs.python.org/tut/>, from
beginning to end, running every example and experimenting until you
understand why it does what it does, before moving onto the next.
