Q:
Getting the key to the maximum component of a tuple in a dictionary of tuples
I have a dictionary whose components are all 2-tuples (all integers) and I want to find the key to the tuple with the largest second component. How can I do this in Python 2.6?

Does PIL (Python Imaging Library) have methods to draw linear gradients or/and set clipping paths?
I've looked everywhere but I can't find any examples that demonstrate how to use either. Or are there any other graphics libraries that can do similar tasks?
