I want to insert a delimiter object between every element of a sequence. One way would be:

def join_items(delim, seq):
    result = []
    for x in seq:
        result.append(x)
        result.append(delim)
    if result:
        del result[-1]
    return result

But it seems like there should be a better way. Is there?
