Script still splits final two rows on comma within dollar values
Hello. I hope this is the correct place to provide feedback. In the exercise Read and Write a CSV file (Part 2) the script in the book still splits the final two dollar amounts in the supplier data that contain a comma to indicate thousands. I've re-typed the script from the book, run it from your supplied scripts from the book repository and run it a third time from the current script on the site and continue to receive the same error. The cost data is split across two columns, pushing date into a sixth and seventh column. Is there a subtlety I've missed?
Thanks,
Jay

ValueError: time data '1/20/14' does not match format '%m/%d/%Y'
Hello:
when I run(win8.1 64bit, Spyder 3.2.4, MySQL 5.7.20):
E:>python 4db_mysql_load_from_csv.py supplier_data.csv
it said: "ValueError: time data '1/20/14' does not match format '%m/%d/%Y'", but I changed "str(row[column_index]), '%m/%d/%Y'))" into "str('1/20/2015'), '%m/%d/%Y')) ", it can run , and the result is 👍
