Reading two text files line by line simultaneously
from itertools import izip with open(“textfile1”) as textfile1, open(“textfile2”) as textfile2: for x, y in izip(textfile1, textfile2): x = x.strip() y = y.strip() print(“{0}\t{1}”.format(x, y)) In Python 3, replace itertools.izip with the built-in zip.
