Replacement of zeros X64306
Write a function replacement(f, g) that provided two integer lists f and g returns the list obtained after replacing the zeros in list f with values in g. First zero has to be replaced with the first number in g, the second zero with the second number in g and so on, until there are no more zeros in f or there are no more available numbers in g. When values in g have been exhausted no more replacements are done. Lists f and g do not have to change.
Sample session
>>> replacement([1, -1, 0, 2, 0], [3, -2, 1]) [1, -1, 3, 2, -2] >>> replacement([1, -1, 0, 2, 0], [5]) [1, -1, 5, 2, 0] >>> replacement([1, -1, 0, 2, 0], [0]) [1, -1, 0, 2, 0] >>> replacement([1, -1, 0, 2, 0], []) [1, -1, 0, 2, 0] >>> f, g = [0, 0, -1, 0, 0], [2, 5, 3] >>> replacement(f, g) [2, 5, -1, 3, 0] >>> f == [0, 0, -1, 0, 0] and g == [2, 5, 3] True
