What statements affect the value of rates? Do a text search if you have to. Search for anything that looks like "rates = "... Believe the error message unless something very unusual is happening. Usually, Python is telling you the truth. You _know_ you were dealing with a dictionary earlier. And yet, you also know, from the error message, that something has changed "rates" from a dictionary to a list. What statements in the program could have provoked this? I see at least one in your program that probably will do it. I have no idea what that particular statement is trying to do. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
