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

When there are 1+ items in the list (if not, just use the first element):

>>> "{} and {}".format(", ".join(listy[:-1]),  listy[-1])
'item1, item2, item3, item4, item5, and item6'

Edit: If you need an Oxford comma (didn't know it even existed!) -- just use: ", and" isntead.
