Converting a for loop to a while loop

Question

I am new to Python and I need to convert a for loop to a while loop and I am not sure how to do it. This is what I am working with:

Answer 1

The first answer is the straightforward way, there is another way, if you're allergic to incrementing your index variables:

def scrollList(myList):
  negativeIndices = []
  indices = range(0,len(myList)):
  while indices:
        i = indices.pop();
        if myList[i] < 0:
             negativeIndices.append(i)
  return negativeIndices
