The problem was that you didn't understand that the reason data wasn't what you expected it to be was that you had assigned data to be the fetchall method of the object cur, when what you wanted to do was assign data to be the results of executing the method fetchall on the object cur. Both of these are legal assignments: data = cur.fetchall data = cur.fetchall() However the following is only valid if data is iterable: for row in data: So when it reaches the the line: for row in data: and discovers that data is not an iterable type, it gives an error message. If you can't decipher the error message to get back to the fact that in this case data isn't a y that you can use "for x in y:" to iterate over, and then debug intelligently to determine how any why that error message occurred, then as has been suggested many times in the past, you should stop trying to write code. Seriously, how many other people do you see repeatedly posting "I don't understand the error, help" messages here that have been caused by such simple coding mistakes? Most of us can decipher these error messages ourselves and would be embarrassed to post asking for help. -- Denis McMahon, denismfmcmahon@gmail.com
