Well, a dictionary is by definition unordered, so you will need to
tell python which elements you want, and in which order.

I would do something like this:

####
config = {}
# insert code here to set the values of config

keysToDump = ['test1', 'test2', 'test3']
output = '\\'.join(config[k] for k in keysToDump)
####

(note that, if you are using python2.3 or earlier, you will need to
write that last line as:

output = '\\'.join([config[k] for k in keysToDump])

)

HTH!
