01_dask.delayed.ipynb dask.delayed parallelization section does not have a filenames variable declared

[ghost]

sums = [] counts = [] for fn in filenames: #filenames variable does not exist df = pd.read_csv(fn) by_origin = df.groupby('Origin') total = by_origin.DepDelay.sum() count = by_origin.DepDelay.count() sums.append(total) counts.append(count) total_delays = sum(sums) n_flights = sum(counts) mean = total_delays / n_flights

Are you sure you ran all the notebook cells in order?
