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

like this:

def scrollList(myList):
      negativeIndices = []
      i = 0
      while i < len(myList):
            if myList[i] < 0:
                 negativeIndices.append(i)
            i += 1
      return negativeIndices
