Here is my code up until the point I think I did something weird in this exercise:
#print(daily_sales) daily_sales_replaced = daily_sales.replace(";,;", ";") #print(daily_sales_replaced) daily_transactions = daily_sales_replaced.split(",") #print(daily_transactions) daily_transactions_split =  for i in range(len(daily_transactions)): splitted = daily_transactions[i].split(";") daily_transactions_split.append(splitted) #print(daily_transactions_split) transactions_clean =  for index in range(len(daily_transactions_split)): for words in daily_transactions_split[index]: spliited = words.strip() transactions_clean.append(spliited) print(transactions_clean) customers =  sales =  thread_sold =  for index in range(len(transactions_clean)): if index % 4 == 0: customers.append(transactions_clean[index]) elif (index - 1) % 4 == 0: sales.append(transactions_clean[index]) elif (index - 2) % 4 == 0: thread_sold.append(transactions_clean[index])
The output of transactions_clean was not a 2d list. I got the impression after reading through my tasks that it was meant to be a 2d list with a name, sale, colour thread and date each in its own separate list inside the 2d list.
As it turns out I was fine and managed to get the lists for customers, sales, and threads sold correct anyway. But I’m just wondering now after finishing the exercise how I would have simultaneously made a list which cleaned up daily_transactions_split with strip() and preserved the 2d nature of daily_transactions_split.
Thanks in advance
