我清理了数据文件并对其进行了拆分，使其看起来像这样，
['Arts & Entertainment']
['Arts & Entertainment', 'Animation & Comics']
['Arts & Entertainment', 'Books & Literature']
['Arts & Entertainment', 'Celebrity Gossip']
['Arts & Entertainment', 'Fine Art']
['Arts & Entertainment', 'Humor']
['Arts & Entertainment', 'Movies']
['Arts & Entertainment', 'Movies', 'Action']
['Arts & Entertainment', 'Movies', 'Comedy']
['Arts & Entertainment', 'Movies', 'Documentary']
['Arts & Entertainment', 'Movies', 'Drama']
['Arts & Entertainment', 'Movies', 'Horror']
['Arts & Entertainment', 'Music']
['Arts & Entertainment', 'Music', 'Alternative Music']
['Arts & Entertainment', 'Music', 'Blues']
['Arts & Entertainment', 'Music', 'Christian Music']
['Arts & Entertainment', 'Music', 'Classic Rock']
['Arts & Entertainment', 'Music', 'Classical Music']
['Arts & Entertainment', 'Music', 'Country Music']
['Arts & Entertainment', 'Music', 'Electronic Dance Music']
['Arts & Entertainment', 'Music', 'Heavy Metal']
['Arts & Entertainment', 'Music', 'Pop Music']

现在，我正在尝试将列表对象转换为以下形式的字典，请参见：
{
"Arts & Entertainment": {
"Animation & Comics": {},
"Books & Literature": {},
"Celebrity Gossip": {},
"Fine Art": {},
"Humor": {},
"Movies": {
"Horror": {},
"Action": {},
"Comedy": {}, ...
}, ...
}
问题在于我无法弄清如何不覆盖我的子类别，在上面的示例中，电影子键有三个与之相关的类别，然而当我运行我的代码时，它只有一个"Horror"键，并且这是因为恐怖片是该类别中最后一个元素的最后一个列表中的最后一个元素。下面是我得到的示例：
{
"Arts & Entertainment": {
"Animation & Comics": {},
"Books & Literature": {},
"Celebrity Gossip": {},
"Fine Art": {},
"Humor": {},
"Movies": {
"Horror": {} # notice there are no other categories in the movies section
}, ...
}
我尝试过的代码：
def cleanup_contextweb():
contextweb_file_path = directory_path + raw_file_names[1]
tree = {}
with open(contextweb_file_path, 'r') as contextweb_file:
cats = contextweb_file.read().replace('Manhattan, New York', 'Manhattan New York').replace('Las Vegas, Nevada', 'Las Vegas Nevada').replace('Celebrity/Gossip', 'Celebrity Gossip').replace('Atheism/Agnosticism', 'Atheism Agnosticism').replace('Pagan/Wiccan', 'Pagan Wiccan').split(',')
#cats = re.sub(r'"|\[|\]', '', cats)
cats = [map(str.strip, re.sub(r'"|\[|\]', '', cat).split('/')) for cat in cats]
cats = sorted(cats)
for cat in cats:
if len(cat) == 1:
tree[cat[0]] = {}
elif len(cat) == 2:
tree[cat[0]][cat[1]] = {}
elif len(cat) == 3:
tree[cat[0]][cat[1]] = {}
tree[cat[0]][cat[1]][cat[2]] = {}
elif len(cat) == 4:
tree[cat[0]][cat[1]] = {}
tree[cat[0]][cat[1]][cat[2]] = {}
tree[cat[0]][cat[1]][cat[2]][cat[3]] = {}
with open(directory_path + 'cleaned_' + raw_file_names[1], 'w') as contextweb_file_out:
json.dump(tree, contextweb_file_out, sort_keys=True, indent=4)
return json.dumps(tree, sort_keys=True, indent=4)
你会看到，我正在尝试构建字典，根据传入列表的长度，我知道有多深（需要多少个键）。我尝试过其他方法，但都被删除了，包括对子列表（cats）按子列表长度排序并反转，以便首先迭代所有具有4个元素的列表。我认为我可以通过这种方式构建键，因为键将存在于较低级别。但那并没有真正帮助。
