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

Might as well round out the solutions with a recursive example.

>>> listy = ['item1', 'item2','item3','item4','item5', 'item6']
>>> def foo(a):
    if len(a) == 1:
        return ', and ' + a[0]
    return a[0] + ', ' + foo(a[1:])

>>> foo(listy)
'item1, item2, item3, item4, item5, , and item6'
>>>
