Egzersiz talimatları

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

Use pd.read_csv() to import 'ozone.csv' and set a DateTimeIndex based on the 'date' column using parse_dates and index_col, assign the result to ozone and inspect using .info().
Apply .resample() with weekly frequency ('W') to ozone, aggregate using .mean() and plot the result.
Repeat with monthly ('M') and annual ('A') frequencies, plotting each result.
