Why do I keep getting a list index out of range error in my code?

Here is my csv file:

dan, 12pts

Here is the code and I keep getting an index out of range error in my code? I don't understand what's wrong with it:

import csv

with open('scoreboard.csv','r') as csv_file:
   csv_reader = csv.reader(csv_file)

   for line in csv_reader:
       print(line[1])

Can anyone help?

You have a blank line after the first line in your csv file.

Reproducing your error with appending a blank line after your first row (Note: "<" characters are not the part of the csv file):

< dan, 12pts
<

we get the error message of course:

import csv

with open('scoreboard.txt','r') as csv_file:
   csv_reader = csv.reader(csv_file)

   for line in csv_reader:
       print(line[1])

Out:

print(line[1])

IndexError: list index out of range

For first sight the blank line in a csv file can hide pritty well, but after we delete it (or them!):

< dan, 12pts

Out:

12pts

This is quite possibly due to a blank line in your file, such that there is no second element. To diagnose this, instrument your code with a little extra reporting:

import csv

with open('scoreboard.csv','r') as csv_file:
   csv_reader = csv.reader(csv_file)

   for line in csv_reader:
       print(line)
       print(len(line))
       print(line[1])

This will show you what's going wrong, just before it blows up.
