python: how do i always start from the second row in csv?

Question

b holds the contents of a csv file

i need to go through every row of b; however, since it has a header, i dont want to pay attention to the header. how do i start from the second row?

for row in b (starting from the second row!!):

Answer 1

b.next()
for row in b:
    # do something with row

But consider using the csv module, especially with DictReader.

Answer 2

Easiest way is to use a DictReader. It will consume the first row for you

Answer 3

Prepend a next(b) (in every recent version of Python; b.next() in older ones) to skip the first row (if b is an iterator; if it is, instead, a list, for row in b[1:]:, of course).
