Nope, there is not. I think some might instead use several numbered
options to similar effect:
# config file
[Example]
fruit1: apple
fruit2: orange
fruit3: pear
# Python
from itertools import count
fruits = []
names = ("fruit" + str(i) for i in count(1))
for name in names:
if not config.has_option("Example", name):
break
fruits.append(config.get("Example", name))
Cheers,
Chris
