I am trying to make a 'inventory' type app...
i have it working like i want it to work, adding name of item and serial number of item, but i am trying to add an item and keep getting errors...
if you can look at this and tell me how to change it to view the added item

def list_items(items):
    for i in range(0, len(items)):
        item = items[i]
        print(str(i+1) + ". " + item[0] + " (" + str(item[1]) + ")") 

Thanks in advance

I now have it where it will input the added information in the csv file, but now i can't view it... i can change the 'item[]' or even add an 'item[]' but it states out of range. i think i should simply be able to change the line 'for i in range(0, len(items)):
but can't seem to make it work...

thanks for the help

use difflib: https://docs.python.org/3/library/difflib.html
(or you can use Linux diff from command line)

Hi, Larz60 thanks for the link to it, I was finding the same.

forget my first post, I misunderstood your intent, is this what you're looking for?
(change csv filename to your file, and change delimiter as required)

import os
import csv


os.chdir(os.path.abspath(os.path.dirname(__file__)))

def list_items(row):
    for item in row:
        for element in item:
            print(f"{element} ", end ='')
        print(" | ", end="")
    print()

with open('health-no-head-sample.csv') as fp:
    crdr = csv.reader(fp, delimiter= ',')
    for n, row in enumerate(crdr):
        if n < 10:
            list_items(row)
        else:
            break

results with my csv file:
