In the programme below I am trying to read two csv format files and process

import csv

f2_reader = csv.reader(open(r"Z:\Weka
work\Feature_Vectors_Fullset_00_noxy+class.arff"))
nf = open(r"Z:\Weka work\classified_image00_withoutxy.arff", "w")
while True:
l1 = f1_reader.next()
while len(l1) != 12:
l1 = f1_reader.next()
l2 = f2_reader.next()
while len(l2) != 11:
l2 = f2_reader.next()
ix = l1[0].strip()
iy = l1[1].strip()
classification = l2[8].strip()
print >> nf, ix, iy, classification
nf.close()
This programme is giving me this error now :
Traceback (most recent call last):
File "Z:\Weka work\final_image_classificationwithoutxy.py", line 16, in
<module>
l2 = f2_reader.next()
StopIteration
what could be a possible reason to StopIteration ???
I checked the syntax and usage of this module looks alright to me , but
then why this error ?
That's not an error, it's just a normal way to end a for-loop. If you
were using a syntax like:
for item in f2_reader:
the StopIteration would simply end the loop. Since you're doing it
manually, you have to handle the exception yourself.
