In the documentation, it says that the data brought through fetcher will be parsed into a pandas dataframe object. Whenever I call a pandas method on that dataframe, however, I get an error. How can I successfully call pandas methods on the dataframe?
Any help is appreciated - Jacob
I followed up with Jacob on this one by email. The dataframe that he was referring to is only for the pre_func and post_func functions passed to fetch_csv().

The way i understand it, one has to make any dataframe related calculations at the initial stage with pre_func, then pass them on into handle_data
