Python Sort with multiple keys

This is the sample when sorting with multiple keys in descending order.

    cars = [

      {'car': 'Ford', 'year': 2005},

      {'car': 'Mitsubishi', 'year': 2000},

      {'car': 'Buick', 'year': 2018},

      {'car': 'Buick', 'year': 2019},

      {'car': 'BMW', 'year': 2019},

      {'car': 'Faraday', 'year': 2014},

      {'car': 'VW', 'year': 2011},

      {'car': 'Lincoln', 'year': 2017},

    ]

    print("cars")

    print(*cars, sep="\n")

    cars_sorted = sorted(cars, key = lambda x: ([-ord(c) for c in x["car"]], -x["year"]))

    print("sorted cars")

    print(*cars_sorted, sep="\n")

For string to do reversed order, a little trick is to convert character to ascii code number.

{'car': 'VW', 'year': 2011}
{'car': 'Mitsubishi', 'year': 2000}
{'car': 'Lincoln', 'year': 2017}
{'car': 'Ford', 'year': 2005}
{'car': 'Faraday', 'year': 2014}
{'car': 'Buick', 'year': 2019}
{'car': 'Buick', 'year': 2018}
{'car': 'BMW', 'year': 2019}
