[issue3436] csv.DictReader inconsistency

[Nick Coghlan]

Nick Coghlan <ncoghlan at gmail.com> added the comment:

Like Raymond, I have issues with the idea of implicitly reading the
headers in __init__, but would be fine with the idea of a separate
method in 2.7/3.1.

As far as working around the absence of such a method goes, I personally
use itertools.chain if I happen to need the headers before I start
iterating:

r = csv.DictReader(open('test.csv'))
first = next(r)
# Do something with r.fieldnames
for row in chain(first, r):
    # Do something with each row
