Hi i have following Dictionary.
players = {
"Brazil": [
(12, "Júlio César", "Goalkeeper", []),
(4, "David Luiz", "Defender", []),
(6, "Marcelo", "Defender", []),
(13, "Dante", "Defender", []),
(23, "Maicon", "Defender", []),
(5, "Fernandinho", "Midfielder", []),
(7, "Hulk", "Midfielder", []),
(8, "Paulinho", "Midfielder", []),
(11, "Oscar", "Midfielder", [90]),
(16, "Ramires", "Midfielder", []),
(17, "Luiz Gustavo", "Midfielder", []),
(19, "Willian", "Midfielder", []),
(9, "Fred", "Striker", []),
],
"Germany": [
(1, "Manuel Neuer", "Goalkeeper", []),
(4, "Benedikt Höwedes", "Defender", []),
(5, "Mats Hummels", "Defender", []),
(16, "Philipp Lahm", "Defender", []),
(17, "Per Mertesacker", "Defender", []),
(20, "Jérôme Boateng", "Defender", []),
(6, "Sami Khedira", "Midfielder", [29]),
(7, "Bastian Schweinsteiger", "Midfielder", []),
(8, "Mesut Özil", "Midfielder", []),
(13, "Thomas Müller", "Midfielder", [11]),
(14, "Julian Draxler", "Midfielder", []),
(18, "Toni Kroos", "Midfielder", [24, 26]),
(9, "André Schürrle", "Striker", [69, 79]),
(11, "Miroslav Klose", "Striker", [23]),
],
}
Is it possible to create a dictionary which contains all Brazilian players with the name as key and the first number as value in a one line dictionary comprehension? Output should be:
{'Júlio César': 12, 'David Luiz': 4, 'Marcelo': 6, 'Dante': 13, 'Maicon': 23, 'Fernandinho': 5, 'Hulk': 7, 'Paulinho': 8, 'Oscar': 11, 'Ramires': 16, 'Luiz Gustavo': 17, 'Willian': 19, 'Fred': 9}
Sure it's possible!
brazil = {player: number for (number, player, _, _) in players["Brazil"]}
# {'Júlio César': 12, 'David Luiz': 4, 'Marcelo': 6, 'Dante': 13, 'Maicon': 23, 'Fernandinho': 5, 'Hulk': 7, 'Paulinho': 8, 'Oscar': 11, 'Ramires': 16, 'Luiz Gustavo': 17, 'Willian': 19, 'Fred': 9}
This works by expanding each tuple in the list of tuples from your source data. The key and value you want to use are named, while the underscores are a conventional way of saying you don't want to use those parts of the tuple
