python - 如何通过字典或JSON等似是而非的格式将三个列表合并为一个列表？ Python

Question

我有三个列表:

imglist=['1.jpg', '12.jpg']
classlist=['class1', 'class5']
sentencelist=['Good for health.', 'Good luck.']

如何将列表组合成如下格式？

[ ['1.jpg','class1','Good for health.'],
['12.jpg','class5','Good luck.']]

或者您是否知道如何将列表合并为字典或 JSON 格式？比如

[{'img':'1.jpg','class':'class1','sentence':'Good for health.'},
{'img':'12.jpg','class':'class5','sentence':'Good luck'}]

Answer 1

使用zip()将列表合并为:

>>> imglist=['1.jpg', '12.jpg']
>>> classlist=['class1', 'class5']
>>> sentencelist=['Good for health.', 'Good luck.']

# combining list
>>> zip(imglist, classlist, sentencelist)
[('1.jpg', 'class1', 'Good for health.'), ('12.jpg', 'class5', 'Good luck.')]

要将其转换为您格式的 dict，请使用 zip 和 list comprehension 作为:

>>> key_list = ["img", "class", "sentence"]
>>> my_zipped_list = zip(imglist, classlist, sentencelist)  # same list as above example

>>> [dict(zip(key_list, zipped_element)) for zipped_element in my_zipped_list]
[{'class': 'class1', 'img': '1.jpg',  'sentence': 'Good for health.'},
 {'class': 'class5', 'img': '12.jpg', 'sentence': 'Good luck.'}]
