Good afternoon,
I have a list that I'm iterating thorough in Python. Each item in the list
will have between 1-200 urls associated with it. My goal is to move on to the

Hi,
I'm having difficulty thinking about how to do this as a Python beginner.
But I have a list that is represented as:
[1,2,3,4,5,6,7,8]
and I would like the following results:
[1,2] [3,4] [5,6] [7,8]
Any ideas?
Thanks
