Confused on why my code is coming up with an empty list

I am currently working on this project and got to step 6. I entered my code, which seemed right, and matches the code from the walkthrough video, but it comes up as an empty list when it should be a very full list.

When I print it, the terminal comes up with just “” when it should be 100+ lines of text. I’m very confused on what I’m doing wrong. Anything helps, thank you!

Sorry, will post full code here.

daily_sales_replaced = daily_sales.replace(";,;", "+")

daily_transactions = daily_sales_replaced.split(",")
#print(daily_transactions)

daily_transactions_split = []
for transaction in daily_transactions_split:
  daily_transactions_split.append(transaction.split("+"))
print(daily_transactions_split)```

[toastedpitabread]

daily_transactions = daily_sales_replaced.split(",")
daily_transactions_split = []
for transaction in daily_transactions_split:
    daily_transactions_split.append(transaction.split("+"))

You should think about how the for-loop is working here. for transaction in daily_transactions_split is going to iterate through daily_transactions_split, but what value do you have assigned to it?

[captain_jack]

The transaction is each group of units split by the +

Sorry, I still don’t really understand the issue

I’ll word it differently.

Let’s look at what happens in the code:

• you declare daily_transactions_split to be an empty list
• you write a for-loop that will cycle through daily_transactions_split. But it’s an empty list…

@itsjackbox

What happens when you write this?

for transaction in daily_transactions_split:
   print(transaction)

---

Then consider… what happens when you write this?

for transaction in daily_transactions:
   print(transaction)

Wow I just realized how incredibly wrong I am. Thanks for helping me realize, just a massive brain fart I guess.

[toastedpitabread]

It happens, no worries!

@itsjackbox welcome to the forums!
