Python将字符串解析为字典

Question

我有以下字符串：

"[['Categories', [['180972'], ['180800'], ['16228'], ['32733'], ['32789'], ['32833'], ['325137'], ['32839'], ['25329'], ['42605'], ['428240849'], ['5101'], ['568'], ['570716'], ['57116'], ['57080545404'], ['57083134076']]], ['Tags', ['Stock', 'Color', 'Fam', 'Dress','Maxi']], ['Type', ['Luxary']], ['Vendor', ['AAA']]]"

我想把它解析为dict/json。 最好的方法是什么？你知道吗

Answer 1

这个怎么样

>>> import itertools
>>> import ast
>>> import pprint
>>> i = ast.literal_eval(s)
>>> d = {k[0]:list(itertools.chain(*k[1])) if isinstance(k[1][0], list) else list(k[1]) for k in i}
>>> pprint.pprint(d)
{'Categories': ['180972',
                '180800',
                '16228',
                '32733',
                '32789',
                '32833',
                '325137',
                '32839',
                '25329',
                '42605',
                '428240849',
                '5101',
                '568',
                '570716',
                '57116',
                '57080545404',
                '57083134076'],
 'Tags': ['Stock', 'Color', 'Fam', 'Dress', 'Maxi'],
 'Type': ['Luxary'],
 'Vendor': ['AAA']}
