Thread Shed Project: Task 8 problem


#1

Good morning dear reader :grinning:

First of all: i searched for other posts treating this problem, but no one of these posts gave me the answer to my problem.

After a week of programming i learned quite alot, but now I’m rally stuck in this task:

It looks like each data item has inconsistent whitespace around it. First, define an empty list transactions_clean .

Now, Iterate through daily_transactions_split and for each transaction iterate through the different data points and strip off any whitespace.

Add each of these cleaned up transactions to the new list transactions_clean .

I reached to solve the task and headed on to number 15, but then I realised that my list contains every sale 4 times!
Even with the video (which is good to understand) i could’nt figure out my fault. (But at least i found out that the error must be in step 8)

transactions_clean=[]

for transaction in daily_transactions_split:
  transaction_clean=[]
  for data_point in transaction:
    
    transaction_clean.append(data_point.replace("\n","").strip(' '))
    transactions_clean.append(transaction_clean)

Please help me find the error so that i can carry on :grinning:

Here is my full code for this project
