def __init__(self, name):
self.name = name
return self.name + " " + self.family
family = "McAnt"
family = "O'Ant"
NAMES_URL = "http://www.gro-scotland.gov.uk/files1/stats/pop-names-07-t4.csv"
NAMES_FILENAME = posixpath.basename(NAMES_URL)
if not os.path.exists(NAMES_FILENAME):
names = 
with open(NAMES_FILENAME) as f:
for line in f:
names += line.split(",")[0::3]
names = filter(bool, names)
ants = [random.choice((RedAnt, YellowAnt))(name)
for name in random.sample(names, 20)]
print textwrap.fill(str(ants), 50)
Let's do a sample run of the script:
$ python ants.py
