我将对象zipped实例化如下：
zipped = zip(_artist_name, _artist_title, _xl, _l, _m, _s)
其中参数均为30个字符串的数组。我有一个字典track_data，在密钥recent_tracks下面，我还有其他键值对，如下所示：
track_data['recent_tracks'] = [
{"artist": ?,
"title": ?,
"image_xl": ?,
"image_l": ?,
"image_m": ?,
"image_s": ?}
]
我希望track_data['recent_tracks']包含30个对象，其中每个对象包含6个子对象。有点像这样：
object 1 - artist
title
xl
l
m
s
object 2 - artist
title
xl
l
m
s
我之前的方法与上面的示例类似，但它只创建了一个包含30个对象的6个数组的对象。如何遍历压缩项以将正确的值分配给30个单独对象中的相应对？
答案 0 :(得分：2)
添加密钥并为每个zipped条目生成字典：
track_keys = ("artist", "title", "image_xl", "image_l", "image_m", "image_s")
zipped = zip(_artist_name, _artist_title, _xl, _l, _m, _s)
track_data['recent_tracks'] = [dict(zip(track_keys, values)) for values in zipped]
演示：
>>> _artist_name = ['artist {}'.format(i + 1) for i in range(30)]
>>> _artist_title = ['title {}'.format(i + 1) for i in range(30)]
>>> _xl = ['xl image {}'.format(i + 1) for i in range(30)]
>>> _l = ['l image {}'.format(i + 1) for i in range(30)]
>>> _m = ['m image {}'.format(i + 1) for i in range(30)]
>>> _s = ['s image {}'.format(i + 1) for i in range(30)]
>>>
>>> from pprint import pprint
>>> track_keys = ("artist", "title", "image_xl", "image_l", "image_m", "image_s")
>>> zipped = zip(_artist_name, _artist_title, _xl, _l, _m, _s)
>>> pprint([dict(zip(track_keys, values)) for values in zipped])
