I am reading a file with Dictreader and writing a new file. I want use the
fieldnames in the Dictwriter from the reader. See below How should I be
doing this?
See how I am using reader.fieldnames in the the Dictwriter. I get an error
(below)
with open(readfile, 'r', encoding='utf-8', errors='ignore', newline='') as
csvread:
reader = DictReader(csvread)
with open(writefile, 'w') as csvwrite:
writer = DictWriter(csvwrite, delimiter=',',
fieldnames=reader.fieldnames)
for line in reader:
pass
ValueError Traceback (most recent call
last)<ipython-input-13-0dac622bb8a9> in <module>()----> 1

/Users/vmd/anaconda/envs/py34/lib/python3.4/csv.py in fieldnames(self)

try:---> 96 self._fieldnames = next(self.reader)
