Hi - Beginner question here. I'm working with ConfigParser. I'd like
to take a multiline variable and convert it directly to an array.
Seems like a common problem, but I don't see how I can do it without
doing a little parsing in my own code. Here's what I'm doing ...

>>> import ConfigParser
>>> import io
>>> sample = """
.... [Example]
.... fruit = apple
.... orange
.... pear
.... """
>>> config = ConfigParser.RawConfigParser()
>>> config.readfp(io.BytesIO(sample))
>>> config.get("Example", "fruit")
'apple\norange\npear'
>>> temp = config.get("Example", "fruit")
>>> temp.split()
['apple', 'orange', 'pear']

I'm thinking there's a way to avoid this intermediate temp.split()
step. Is there not a way to move a multiline value straight into an
array using ConfigParser?

Thanks for the help.

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

Ok, thanks Chris. Maybe I'm getting too lazy in my old age.
