This module is pretty self-explanatory.

>>> from eng_join import join

>>> join(['blue', 'red', 'yellow'], conj='or', im_a_moron=True)
'blue, red or yellow'

>>> join(['blue', 'red', 'yellow'], conj='or')
'blue, red, or yellow'

>>> join(['blue', 'red'], conj='or')
'blue or red'

>>> join(['blue', 'red'], conj='and')
'blue and red'

>>> join(['blue'], conj='and')
'blue'

>>> join(['blue', 'red', 'yellow', 'green', 'yellow'], conj='and')
'blue, red, yellow, green, and yellow'

im_a_moron removes support for the Oxford comma. I have opinions.

$ pip install eng_join
