itertools - using python's 'with' while reading two files simultaneously with izip -

-

i regularly use python read 2 or more files simultaneously in following way:

for line1, line2 in izip(open(file1),open(file2)):     line1 , line2

(using izip itertools package because files i'm reading huge , don't want load entire file memory).

i have been converted using with while reading files, apparently better since close open files if program crashes (at least that's understand discussion on here , other places):

with open(filename) fh:     line in fh:         line

however, can't seem figure out how combine these 2 methods. when trying use izip in context, says 'itertools.izip' object has no attribute '__exit__' intuit part of reason why using with powerful.

so, there anyway use izip with?

you'll kick when see how obvious :

with open(fname1) f1, open(fname2) f2:     line1, line2 in izip(f1, f2):          ...
