Solve the following python programming problem given the following code:
def _gen_ridge_line(start_locs, max_locs, length, distances, gaps) : 
    "
    Generate coordinates for a ridge line.

    Will be a series of coordinates, starting a start_loc (length 2).
    The maximum distance between any adjacent columns will be
    `max_distance`, the max distance between adjacent rows
    will be `map_gap'.

    `max_locs` should be the size of the intended matrix. The
    ending coordinates are guaranteed to be less than `max_locs`,
    although they may not approach `max_locs` at all.

    def keep_bounds(num, max_val) : 
        out = max (num, 0) 
        out = min (out, max_val) 
        return out 
gaps = copy.deepcopy (gaps) 
    distances = copy.deepcopy (dist_int) 
    locs = np.zeros ([length, 2], dtype = int) 
    locs [0, :] = start_locs 
    total_length = ((max_locs [0] - start_locs [0]) - sum (gaps)) 
    if (total_length < length) : 
        raise ValueError ('Cannot generate ridge line according to constraints') 
dist_int = ((length / len (distances)) - 1) 
    gap_int = ((length / len (gaps)) - 1) 
    for ind in xrange (1, length) : 
        nextcol = locs [((ind - 1), 1)] 
        nextrow = (locs [((ind - 1), 0)] + 1) 
        if (((ind % dist_int) == 0) and (len (distances) > 0)) : 
            nextcol += (((- 1) ** ind) * distances.pop ()) 
if (((ind % gap_int) == 0) and (len (gaps) > 0)) : 
            nextrow += gaps.pop ()

#Here is Python program to fix the buggy line: distances = copy.

distances = copy.deepcopy (distances)
