yes, but it wasn't "zip" I guess, just got introduced in Python 2.0

I thought, dict(zip(listOfKeys, listOfValues)) is the common idiom to 
initialize a dict from a keylist and valuelist. But, as you said, you can 
write above of course as

for name, value in zip(msg["fieldnames"], fieldvalues):
	appli[name] = value

... not all my code is nice and beautiful ;-)
