Python IndexError: list out of range error

I have the python script written as : 

import csv
with open ("ann.csv", "r") as csvfile:
    reader = csv.reader(csvfile)
    collected = []
    for row in reader:
        collected.append(row[0])
    print (",".join(collected))

ann.csv file as : 

colums_header
7432
7849
7844
7108
8712
7833
7842
8723
7895
8719
9899
7352
7515
7252
8906
continued

When I try to run the python script it gives error : 

Traceback (most recent call last):
  File "columnTorow.py", line 6, in <module>
    collected.append(row[0])
IndexError: list index out of range

Why am I getting the out of range exception?

The reason is you have an empty line somewhere in the middle of the file or at the end of the file. You should add a condition checking before adding the item to your list like this:

for row in reader:
    if row:
        collected.append(row[0])

Hope this helps.
