Thanks for another informative video! There is one tiny concern with the append_to_csv code. The file lacks the normal (but optional per RFC 4180) header that some apps expect or that may be needed if there were more fields in the file. This small change would create the header line just once when the file is created. Before the with block simply add this little bit of code: # Check if the file exists if not os.path.exists('append.csv'): # Open file in write mode to write the header line with open('append.csv', 'w') as f: writer = csv.DictWriter(f, field_names) writer.writeheader()

Wouldn't the clean_data function also remove the word "Item" and "$" from the name of the product too?

John, Another great presentaion! Also the program is very logically developed. I liked to see list compressions. Another idea I think. Could have a GUI front end where user inputs some conditions or product categories or names or whatever, and the program returns records based on the conditions either one at a time or in a table on the form. Just a thought. Thanks!
