USING PYTHON 2

Give two lists sorted in increasing order, create and return a merged list of all the elements in sorted order. You may modify the passed in lists. Ideally, the solution should work in "linear" time, making a single pass of both lists.

Example:

def merge_list (list_one, list_two)

print (merge_list ([1,3,5], [7,2,9])) - [1,2,3,5,7,9]
