Why is impPixel = row[8] out of range and is nesting if statements okay in python?

Question

I am beginner to python but have two questions

I am writing a script to search through an excel file and read how many good https requests I receive. All my functions seem to work until it's time to access the excel file. One of error I see is :

['urlRequest.py']
('What is:', ['import csv'])
Traceback (most recent call last):
  File "urlRequest.py", line 100, in <module>
    impPixel = row[8]
IndexError: list index out of range

I know trying to access a list won't happen if I tried to access for example:

list['cookies','baker','kitchen]
# accessing list[0],list[1], list[2] , 
# will return an element but list[3] will throw an out of range error.

Also, I printed row before my loop and I don't understand the error it gives:

['import csv']

I looked at my excel file and it doesn't seem to be out of range. Any help would be appreciated.

Thirdly -----> I am not sure if I am using my nested if statements correctly.

Here is the current state of my code:

import sys
import csv
import requests

from requests.exceptions import ConnectionError
