Dear All,
I have noticed this odd behaviour in the CSV DictReader
Class, and at a loss to understand/ get around it.
The aim is to read in a CSV file, and then iterate over
the lines. The problem (seems) to be that once you have
iterated over it once, you can't do it again.
I don't know if this is me (and it may well be) but it
seems to be a recurrent issue, and means that a
csv.DictReader doesn't behave in the same way as a normal
dict object.
Code to confirm/ replicate below.
What I'm looking for is a way to explicity reset the
iterator, to tell it to go back to the beginning.
Any ideas (or pointing out I am a moron) very welcome.

import csv
fname = "insert your csv file here.csv"
inr = csv.DictReader(open(fname, 'r'), delimiter = ',',
quotechar = '"')
for r in inr:
print r
<Get your rows here>
for r in inr:
print r
Nothing.....
If I reload the file, I can solve the issue
