Using python, how to read a file starting at the seventh line ?

with open('dwn.txt') as f:
    for i in xrange(6):
        f, next()
    for line in f:
        process(line)

Update: use next(f) for python 3.x.

Itertools answer!

from itertools import islice

with open('foo') as f:
    for line in islice(f, 6, None):
        print line
