附加到字典中的列表 [英] Append to a list within a dictionary

问题描述

我想获得输出像

{'episodes': [{'season': 1, 'plays': 0, 'episode': 11}, {'season': 2, 'plays': 0, 'episode': 1}], 'title': 'SHOWNAME1', 'imdb_id': 'tt1855924'} 
{'episodes': [{'season': 4, 'plays': 0, 'episode': 11}, {'season': 5, 'plays': 0, 'episode': 4}], 'title': 'SHOWNAME2', 'imdb_id': 'tt1855923'} 
{'episodes': [{'season': 6, 'plays': 0, 'episode': 11}, {'season': 6, 'plays': 0, 'episode': 12}], 'title': 'SHOWNAME3', 'imdb_id': 'tt1855922'}

但是当我需要附加到字典中的值时，我被卡在追加行上。
如果标题不在字典中，则会为该标题创建第一个条目

but I am stuck on the append line as I need to append to a value inside the dictionary. If title is not in the dictionary it creates the first entry for that title

{'episodes': [{'season': 1, 'plays': 0, 'episode': 12}], 'title': 'Third Reich: The Rise & Fall', 'imdb_id': 'tt1855924'}

然后如果同样的标题再次出现我想要季节，剧集和剧本被插入现有的行。然后，脚本将执行下一个节目，并创建一个新条目或再次附加，如果已经有该标题的条目....等等

Then if the same title appears again I want season, episode and plays to be inserted into the existing line. The script would then do the next show and either create a new entry or append again if there is already en entry for that title.... and so on

if 'title' in show and title in show['title']:
    ep = {'episode': episode, 'season': season}
    ep['plays'] = played
    ?????????????????????.append(ep)
else:
    if imdb_id:
        if imdb_id.startswith('tt'):
            show['imdb_id'] = imdb_id
    if thetvdb != "0":
        show['tvdb_id'] = thetvdb

    if title:
        show['title'] = title
    ep = {'episode': episode, 'season': season}
    ep['plays'] = played
    show['episodes'].append(ep)

感谢Martijn Pieters，I现在有这个

Thanks Martijn Pieters, I now have this

    if title not in shows:
        show = shows[title] = {'episodes': []}  # new show dictionary
    else:
        show = shows[title]
    if 'title' in show and title in show['title']:
            ep = {'episode': episode, 'season': season}
            ep['plays'] = played
            show['episodes'].append(ep)
    else:

这给了我想要的输出，但只是想确保它看起来正确

This give me the output I wanted but just wanted to make sure it looked correct

推荐答案

你需要存储您的匹配在字典中，而是按标题键入。如果您多次在文件中遇到相同的节目，您可以再次找到相同的节目：

You need to store your matches in a dictionary instead, keyed by title. You can then find the same show again if you encounter it in your file more than once:

shows = {}

# some loop producing entries
    if title not in shows:
        show = shows[title] = {'episodes': []}  # new show dictionary
    else:
        show = shows[title]

    # now you have `show` dictionary to work with
    # add episodes directly to `show['episodes']`

收集所有节目后，请使用 shows.values（）提取所有显示词典作为列表。

After collecting all your shows, use shows.values() to extract all show dictionaries as a list.
