Python provides both while loops and for loops for repetition of code. Briefly compare these two control flow constructs. What situations are better suited for each? Suppose you have a list of integers. When using a for loop, you can either iterate over the index values of the list or iterate over the list elements themselves. Briefly explain (or give a small example) when you would iterate over the index values and when you would iterate over the elements themselves. [1 mark for each.]
