In the programme below I am trying to read two csv format files and process
them and write a new file with some of theirs data.
import csv
f1_reader = csv.reader(open(r"Z:\Weka
work\Feature_Vectors_Fullset_00.arff"))
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 ?
Thankyou in Advance
