CSV - List Index Out Of Range

I get this error reading CSV file (no headers, 3 columns, 2nd and 3rd strings): Traceback (most recent call last): File 'C:\Python32\fantasy.py', line 72, in module> some=row[1]

Solution 1:

Try checking for blank lines. Also, avoid using file as a variable name. "r" is the default mode with open.

import csv

with open(r"C:\Users\me\Desktop\file-2.csv") as f:
     reader = csv.reader(f, delimiter=',', quotechar='"')
     for row in reader:
        if row:
            some=row[1]

Solution 2:

It looks like you have an empty line or something. By default each iteration of your for loop grabs a line of text from your csv file. That row of text ends with a newline character. So if you have a blank line then the reader reads it as something like this [].

Do this and you will see what I mean:

for row in reader:
    print(repr(row))
    some = row[1]

You will find that the last row that gets printed is not of length 2 or more.

There are a few things you can do to fix this:

1. Pass the file through some cleanup script to remove blank lines
2. change the recognized newline character when you call reader

Solution 3:

This question is old, but I ran into a slightly different solution to this problem so I will put it here for anyone else who might have this problem. My file was so large I could not see the end of it. At the end there was a row with only 2 things in it instead of the typical 5 of my file so when I tried to get the fourth column it was giving me this error. Here was my solution:

    for row in reader:
        if len(row) > 2:
            array.append(row[3])

Solution 4:

I've had this error before as well. My issue was stupid and avoidable though. I copied some code from another program and didn't change the delimiter (in my case from pipe to comma), so of course it was going beyond it's index looking for a pipe when one never existed.
