Make a list with a count of wins for each director that won an Oscar-CodePudding

New to programming and tried to find solution but keep on not getting it right. Trying to make a list with the count of Oscar wins for the directors in the list.

**Input**
winners = {1931: ['Norman Taurog'], 1932: ['Frank Borzage'], 1933: ['Frank Lloyd'], 1934: ['Frank Capra'], 1935: ['John Ford'], 1936: ['Frank Capra'], 1937: ['Leo McCarey'], 1938: ['Frank Capra'], 1939: ['Victor Fleming'], 1940: ['John Ford'], 1941: ['John Ford'], 1942: ['William Wyler'], 1943: ['Michael Curtiz'], 1944: ['Leo McCarey'], 1945: ['Billy Wilder'], 1946: ['William Wyler'], 1947: ['Elia Kazan'], 1948: ['John Huston'], 1949: ['Joseph L. Mankiewicz'], 1950: ['Joseph L. Mankiewicz'], 1951: ['George Stevens'], 1952: ['John Ford'], 1953: ['Fred Zinnemann'], 1954: ['Elia Kazan'], 1955: ['Delbert Mann'], 1956: ['George Stevens'], 1957: ['David Lean'], 1958: ['Vincente Minnelli'], 1959: ['William Wyler'], 1960: ['Billy Wilder'], 1961: ['Jerome Robbins', 'Robert Wise'], 1962: ['David Lean'], 1963: ['Tony Richardson'], 1964: ['George Cukor'], 1965: ['Robert Wise'], 1966: ['Fred Zinnemann'], 1967: ['Mike Nichols'], 1968: ['Carol Reed'], 1969: ['John Schlesinger'], 1970: ['Franklin J. Schaffner'], 1971: ['William Friedkin'], 1972: ['Bob Fosse'], 1973: ['George Roy Hill'], 1974: ['Francis Ford Coppola'], 1975: ['Milos Forman'], 1976: ['John G. Avildsen'], 1977: ['Woody Allen'], 1978: ['Michael Cimino'], 1979: ['Robert Benton'], 1980: ['Robert Redford'], 1981: ['Warren Beatty'], 1982: ['Richard Attenborough'], 1983: ['James L. Brooks'], 1984: ['Milos Forman'], 1985: ['Sydney Pollack'], 1986: ['Oliver Stone'], 1987: ['Bernardo Bertolucci'], 1988: ['Barry Levinson'], 1989: ['Oliver Stone'], 1990: ['Kevin Costner'], 1991: ['Jonathan Demme'], 1992: ['Clint Eastwood'], 1993: ['Steven Spielberg'], 1994: ['Robert Zemeckis'], 1995: ['Mel Gibson'], 1996: ['Anthony Minghella'], 1997: ['James Cameron'], 1998: ['Steven Spielberg'], 1999: ['Sam Mendes'], 2000: ['Steven Soderbergh'], 2001: ['Ron Howard'], 2002: ['Roman Polanski'], 2003: ['Peter Jackson'], 2004: ['Clint Eastwood'], 2005: ['Ang Lee'], 2006: ['Martin Scorsese'], 2007: ['Ethan Coen', 'Joel Coen'], 2008: ['Danny Boyle'], 2009: ['Kathryn Bigelow'], 2010: ['Tom Hooper']}


best_director = []
for year, winnerlist in best_director:
    for winner in winnerlist:
        best_director[winner] = 1
    else:
        best_director[winner]  = 1

print("Top winning director = {}".format(best_director))

**Output**
Top winning director = []

CodePudding user response：

You can use collections.Counter along with itertools.chain will get all the names together:

result = Counter(chain(*winners.values()))

Counter({'John Ford': 4, 'Frank Capra': 3, 'William Wyler': 3, 'Leo McCarey': 2, 'Billy Wilder': 2, 'Elia Kazan': 2, 'Joseph L. Mankiewicz': 2, 'George Stevens': 2, 'Fred Zinnemann': 2, 'David Lean': 2, 'Robert Wise': 2, 'Milos Forman': 2, 'Oliver Stone': 2, 'Clint Eastwood': 2, 'Steven Spielberg': 2, 'Norman Taurog': 1, 'Frank Borzage': 1, 'Frank Lloyd': 1, 'Victor Fleming': 1, 'Michael Curtiz': 1, 'John Huston': 1, 'Delbert Mann': 1, 'Vincente Minnelli': 1, 'Jerome Robbins': 1, 'Tony Richardson': 1, 'George Cukor': 1, 'Mike Nichols': 1, 'Carol Reed': 1, 'John Schlesinger': 1, 'Franklin J. Schaffner': 1, 'William Friedkin': 1, 'Bob Fosse': 1, 'George Roy Hill': 1, 'Francis Ford Coppola': 1, 'John G. Avildsen': 1, 'Woody Allen': 1, 'Michael Cimino': 1, 'Robert Benton': 1, 'Robert Redford': 1, 'Warren Beatty': 1, 'Richard Attenborough': 1, 'James L. Brooks': 1, 'Sydney Pollack': 1, 'Bernardo Bertolucci': 1, 'Barry Levinson': 1, 'Kevin Costner': 1, 'Jonathan Demme': 1, 'Robert Zemeckis': 1, 'Mel Gibson': 1, 'Anthony Minghella': 1, 'James Cameron': 1, 'Sam Mendes': 1, 'Steven Soderbergh': 1, 'Ron Howard': 1, 'Roman Polanski': 1, 'Peter Jackson': 1, 'Ang Lee': 1, 'Martin Scorsese': 1, 'Ethan Coen': 1, 'Joel Coen': 1, 'Danny Boyle': 1, 'Kathryn Bigelow': 1, 'Tom Hooper': 1})

And to get the "best" director just use Counter.most_common:

result.most_common(1)[0][0]

John Ford

Edit: You can also just use statistics.mode along with itertools.chain if you only want the most common name:

mode(chain(*winners.values()))

John Ford

CodePudding user response：

You need to iterate over the items of winners:

for year, winnerlist in winners.items():

You'll also need to make best_director a dictionary instead of a list. You will also need to check if a director already exists in best_director and if not set the initial value otherwise increment the count. Alternatively, you could use a Counter.

CodePudding user response：

Alternatively you can use DefaultDict from collections module

from typing import DefaultDict

director_count = DefaultDict(int)
for year, winnerlist in winners.items():
    for winner in winnerlist:
        director_count[winner]  = 1

count_map = DefaultDict(list)

for director, count in director_count.items():
    count_map[count].append(director)

print("Top winning director = {}".format(count_map[max(count_map)]))

Output:

Top winning director = ['John Ford']

Lets get the values for the variables

print(director_count)
print(count_map)

Output:

Try get:

best_director = {}
for year, winnerlist in winners.items():
    for winner in winnerlist:
        best_director[winner] = best_director.get(winner, 0)   1

print("Top winning director = {}".format(max(best_director, key=lambda x: best_director[x])))
