Here is my attempt to merge 10 files stored in a folder into a single file :

import csv

with open("C:\Users\inshu.chauhan\Desktop\test.arff", "w") as w:
    writer = csv.writer(w)
    for f in glob.glob("C:\Users\inshu.chauhan\Desktop\For
Model_600\*.arff"):
        rows = open(f, "r").readlines()
        writer.writerows(rows)


Error:

Traceback (most recent call last):
  File "C:\Users\inshu.chauhan\Desktop\Mergefiles.py", line 3, in <module>
    with open("C:\Users\inshu.chauhan\Desktop\test.arff", "w") as w:
IOError: [Errno 22] invalid mode ('w') or filename:
'C:\\Users\\inshu.chauhan\\Desktop\test.arff'

Why my programme is not working ?? :(

Thanks in Advance !!
