need help on csv based program

I have watched the video, did the program as below.

import csv

with open("Book1.csv", newline='') as csvfile: reader = csv.DictReader(csvfile,delimiter='|') rows = list(reader) for row in rows[1:]: print(row['id'])

Output:Traceback (most recent call last): File "C:\Users\Admin PC\Desktop\csv_sample.py", line 9, in <module> print(row['id']) KeyError: 'id'

so,then I have printed 'print(row)', it returns OrderedDict([('id,name,graduation,percentage,specialization', '122,chinni,m.tech,77,ece')]), Can anybody explain why dict doesn't returning individual tuples?

Hi Vinay,

Could you please reformat the code in your question using this guide to formatting? Also, what video did you watch?

Looking over the documentation, it looks like DictReader produces a dictionary with keys of column names. I believe the issue here is that you've then used the list() function on the dictionary; something like the following might be what you're looking for?

import csv
with csv.DictReader(open("Book1.csv")) as csvfile:
  for row in csvfile:
    print(row["id"])
