Exercise instructions

We have again imported pandas as pd and matplotlib.pyplot as plt for you.

  • Use pd.read_csv() to import 'stocks.csv' and set a DateTimeIndex based on the 'date' column using parse_dates and index_col, assign the result to stocks and inspect using .info().
  • Create monthly_average by applying .resample() with monthly frequency to data, using .mean() to aggregate. Plot the result using subplots.
