transactions_clean = []
for tr in daily_transactions_split:
  for space in range(len(tr)):
    tr[space] = tr[space].strip()
    transactions_clean.append(tr)   

    
customers = []
sales = []
thread_sold = []

for trans in transactions_clean:
  if trans[0] in trans:
    name = trans[0]
    customers.append(name)
    
for sale in transactions_clean:
  if sale[1] in sale:
    price = sale[1]
    sales.append(price)

for thread in transactions_clean:
  if thread[2] in thread:
    thread_type = thread[2]
    thread_sold.append(thread_type)

When I print my individual lists to the console, the individual lists print out a list of each name, sale, and thread four times in what seems like an almost never ending repetition of the individual lists.

['white', 'white', 'white', 'white', 'white&blue', 'white&blue', 
'white&blue', 'white&blue', 'white&blue', 'white&blue', 'white&blue',
 'white&blue', 'white', 'white', 'white', 'white', 'white&yellow',
 'white&yellow', 'white&yellow', .....]```

Not sure if this is caused by the previous transaction_clean code where each individual transaction was stripped of it’s white space and placed into individual transactions lists, but the lists were repeated three times.

[['Edith Mcbride', '$1.21', 'white', '09/15/17'], ['Edith Mcbride', '$1.21', 'white', '09/15/17'], ['Edith Mcbride',
 '$1.21', 'white', '09/15/17'], ['Edith Mcbride', '$1.21', 'white', 
'09/15/17'], 

I am fairly sure this was not the intended output for the desired code and was wondering if anyone can help point me in the write direction.

transactions_clean.append(tr)

The above line is nested inside two loops, hence the repetition.

Thank you!

It is small things like this I notice myself looking over. I appreciate the reply.
