Converting a list into comma-separated string with “and” before the last item - Python 2.7

Question

I have created this function to parse the list:

listy = [\'item1\', \'item2\',\'item3\',\'item4\',\'item5\', \'item6\']


def coma(abc):
    for i in abc[0:-         


        

Answer 1

I cannot take full credit but if you want succinct -- I modified RoadieRich's answer to use f-strings and also made it more concise. It uses the solution by RootTwo given in a comment on that answer:

def join(items):
    *start, last = items
    return f"{','.join(start)}, and {last}" if start else last
