我有不同对象的产品信息、产品描述和产品亮点。这两个对象都有 product_id,所以我可以将它们关联在一起。
decription_items是字典列表,例如:
[
{'product_id': '123', 'description': 'desc1', 'price': '$40' },
{'product_id': '124', 'description': 'desc2', 'price': '$50' },
{'product_id': '125', 'description': 'desc3', 'price': '$99' },
]
product_highlight_dictProductHighlight是 (product_id, )的字典
{
'123': <product_123_highligh>,
'124': <product_124_highligh>,
'125': <product_125_highligh>,
}
最后ProductHighlight是一个类:
class ProductHighlight:
def __init__(self, product_id, location, area):
self.product_id = product_id
self.location = location
self.area = area
我想做的是合并这两种类型并写入一个xml文档,在下面的代码中,我可以合并这两种类型:
for description_item in self.decription_items:
product_id = .get('product_id')
if product_id:
product_highlight = spider.product_highlight_dict.get(product_id)
# I don't know how to combine description_item and
# product_highlight and write them to an xml
更新
我使用以下代码写入product_highlight_dictxml。我不知道如何包含description_item在以下逻辑中?
highlights = []
for k in self.product_highlight_dict:
highlights.append(vars(self.product_highlight_dict[k]))
xml = dicttoxml.dicttoxml(highlights, custom_root='product_highlights')
file = open('filename', "wb")
file.write(xml)
file.close()
