RE: Programming Diary #14: Historical graphing and helpful descriptions

Thanks for your update.
I don't have much time now, but I wanted to briefly comment to your Python problem:
Sometimes Steemchiller adds or changes fields with the result that the number of "columns" and order changes.
For this he adds the entry cols. The safest way to access the data is therefore e.g.: rows[0][cols["author"]].
Then the order doesn't really matter and only a change in the field name can cause complications. However, he announces this early on.
