Question

You will need to define 2 Python functions. These functions could be used by a website tracking movie data. Each movie is represented as a dictionary containing three keys:/p>

the key "film" whose value is a string representing the name of the film;

the key "tomat" whose value is am int of its rating from a well-known website;

the key "gross" whose value is a float equalling its worldwide gross income (in million of dollars).

First, define a key selector function named gross. This function returns a result allowing the built-in sorting function to order dictionaries from the one with the lowest gross income to the dictionary with the greatest gross income.

Next, define another function named sortByGross. This function has a single parameter. This parameter will be a list of movie dictionaries. Your function will result in the list's dictionaries being ordered from the dictionary with the smallest gross to the dictionary with the greatest gross.

Examples:

gross({ "film":"WALL-E", "tomat" : 96, "gross" : 521.28}) would evaluate to 521.28

gross({ "film":"1 Day", "tomat" : 37, "gross" : 55.24}) would evaluate to 55.24

movies = [{"film":"WALL-E", "tomat" : 96, "gross" : 521.28},

{ "film":"Letters to Juliet", "tomat" : 40, "gross" : 79.18},

{ "film":"Twilight", "tomat" : 49, "gross" : 376.66},

{ "film":"The Time Traveler's Wife", "tomat" : 38, "gross" : 101.33}]

sortByGross(movies)

print(movies)

would result in the following output:

[ { 'film':'Letters to Juliet', 'tomat' : 40, 'gross' : 79.18},

{ 'film':'The Time Traveler's Wife', 'tomat' : 38, 'gross' : 101.33},

{ 'film':'Twilight', 'tomat' : 49, 'gross' : 376.66},

{ 'film':'WALL-E', 'tomat' : 96, 'gross' : 521.28}]
