The shop was closed on some days, so those dates are missing from daily. Store a daily Series of sales from 1 to 8 March with the missing days filled with 0 in result.
import pandas as pd
daily = pd.DataFrame({
"date": pd.to_datetime(["2025-03-01", "2025-03-02", "2025-03-04", "2025-03-05", "2025-03-08"]),
"sales": [1200, 950, 1100, 1300, 1700],
})Store your final answer in a variable named result.
