reading lines 2 at a time

Question

Is there a better way to read lines two at a time from a file in python than:

with open(fn) as f:
    for line in f:
        try:
            line2 = f.next(         


        

Answer 1

You could possibly make it more clear with a generator:

def read2(f):
    for line in f:
        try:
            line2 = f.next()
        except StopIteration:
            line2 = ''

        yield line, line2

with open(fn) as f:
    for line1, line2 in read2(f):
        print line1
        print line2
