list index out of range python txt

Question

I have txt file which looks like:

New York,cinema,3,02/04/2022

But I've got error in list, even if this code works to another txt files without date, what's the problem?

def finished_objects():

   file = open("finished_objects.txt", "r",encoding="UTF8")
   lines = file.readlines()
   L = []  # assign empty list with name 'L'
   for line in lines:
       L.append(line.replace("\n", "").split(","))
   file.close()
   for i in range(len(L)):
       print(L[i][0], ":", L[i][1], ". Quantity:", L[i][2], ". Date: ", L[i][3])    
   return L

Answer 1

You can also use "with" for opening files like,

with open("finished_objects.txt", "r",encoding="UTF8") as file:
  lines = file.readlines()
   L = []  # assign empty list with name 'L'
   for line in lines:
       L.append(line.replace("\n", "").split(","))
   # rest of your code

That way you don't have to manage the connection.

Works fine on my end. Might be that your file has one entry with less commas than others. You could do a simple if len(L) != 4 inside your last loop to make sure you won't get errors while running.
