Why is my For Loop multiplying every String

Im trying a python exercise where you are supposed to clean and list a huge string. Im facing a problem which is that my last for loop is making every string appears multiple times.

I have already tried to copy exactly what they do on the walkthough video (https://www.youtube.com/watch?v=x1AxPYJwHCw&feature=youtu.be&t=300)

daily_sales = \`enter code here`

# Start coding below!
daily_sales_replaced = daily_sales.replace(';,;','+')
daily_transactions = daily_sales_replaced.split(',')
daily_transactions_split = []
for transaction in daily_transactions:
  daily_transactions_split.append(transaction.split('+'))

print(daily_transactions_split)

transactions_clean = []
for transaction in daily_transactions_split:
  transaction_clean = []
  for data_point in transaction:
    transaction_clean.append(data_point.strip(" "))
    transactions_clean.append(transaction_clean)

print(transactions_clean)

if you run the print function at the end you will se that the result is something like this:

[['Edith Mcbride', '$1.21', 'white', '\n09/15/17'], ['Edith Mcbride', '$1.21', 'white', '\n09/15/17'], ['Edith Mcbride', '$1.21', 'white', '\n09/15/17'], ['Edith Mcbride', '$1.21', 'white', '\n09/15/17'], ['Herbert Tran', '$7.29', '\nwhite&blue', '09/15/17'], ['Herbert Tran', '$7.29', '\nwhite&blue', '09/15/17'], ['Herbert Tran', '$7.29', '\nwhite&blue', '09/15/17'], ['Herbert Tran', '$7.29', '\nwhite&blue', '09/15/17'],...

The expected would be that every name, price, etc appeared only once
