Question

我需要将此文件内容转换为字典，以便dict中的每个键都是电影的名称，每个值都是在集合中播放的actor的名称。我考虑过阅读文件，将每个电影名称放在一个列表中，然后将其设置为删除重复项。然后，一个循环使每个电影名称成为关键，问题是接下来的问题？怎么做我把值设为演员姓名？

评论：它是一个文本文件（.txt）文件内容示例：

Tom Hanks, You have got mail, Apollo 13, Sleepless in Seattle, Catch Me If You Can

Answer 1

即使输入是文本文件，也可以使用Python csv模块读取它，因为它看起来格式正确，这样做可以处理数据并创建字典本身相对直接

格式化结果有点曲折，因为我希望它只是某种方式 - 但这不是你要问的，对吧？ ;-)

#!/usr/bin/env python2
import csv

# Create and populate the target dictionary from the data in the file.
movie_actors_dict = {}
with open('actors.txt', 'rb') as csvfile:
    for row in csv.reader(csvfile, skipinitialspace=True):
        actor, movies = row[0], row[1:]
        for movie in movies:
            movie_actors_dict.setdefault(movie, set()).add(actor)

# Display resulting dictionary.
print('{')
representation = ',\n'.join(('    {!r}: {{\n'.format(movie)
                             + ',\n'.join('        {!r}'.format(actor)
                                for actor in sorted(movie_actors_dict[movie]))
                             + '\n    }') for movie in sorted(movie_actors_dict))
print(representation)
print('}')

示例输出：

{
    'A Beautiful Mind': {
        'Russell Crowe'
    },
    'A Few Good Men': {
        'Kevin Bacon',
        'Tom Cruise'
    },
    'Ace Ventura': {
        'Jim Carrey'
    },
    'American Gangster': {
        'Denzel Washington',
        'Russell Crowe'
    },
    'Apollo 13': {
        'Tom Hanks'
    },
    'Assassins': {
        'Julianne Moore',
        'Sylvester Stallone'
    },
    'Blood Diamond': {
        'Leonardo Di Caprio'
    },
    'Bone Collector': {
        'Angelina Jolie',
        'Denzel Washington',
        'Morgan Freeman'
    },
    ... etc, etc
}
