Hi,

So I ran this code to help you understand whats happening. I have taken a diabetes dataset from kaggle for reference.

It ended up printing 2 columns:
First column: index number
Second column: the column name

Heres the code:

import csv 
filename = "diabetes.csv" 
with open(filename) as file: 
    data_from_file = csv.reader(file) 
    header_row = next(data_from_file) 
    for index,column_header in enumerate(header_row): 
        print(index,column_header) 

Reference to the dataset:

The output:

Therefore as we can see, 2 columns are printed.

This was a fun question to solve and if there's any doubt please let me know in the comment section.

Thanks and All the Best :D
