# the df has missing values in Prices. In order to umpute values in Prices. We found median price by group, then convert to dict and then change values with median
airline_prices = planes.groupby("Airline")["Price"].median()

print(airline_prices)

# Convert to a dictionary
prices_dict = airline_prices.to_dict()

# Map the dictionary to missing values of Price by Airline
planes["Price"] = planes["Price"].fillna(planes["Airline"].map(prices_dict))
