Grammatical List Join in Python [duplicate]

Answer 1

This expression does it:

print ", ".join(data[:-2] + [" and ".join(data[-2:])])

As seen here:

>>> data
    ['foo', 'bar', 'baaz', 'bah']
>>> while data:
...     print ", ".join(data[:-2] + [" and ".join(data[-2:])])
...     data.pop()
...
foo, bar, baaz and bah
foo, bar and baaz
foo and bar
foo
