Python. How to pull out the dictionary from html?

First, you can use regular expressions to select the desired piece of text:

 import re s = '<div class="subcategory-product-item product_data__gtm-js product_data__pageevents-js ddl_product" data-gtm-position="1" data-list-id="main" data-params=\'{"id":"393591","categoryId":214,"price":2290,"shortName":"Смартфон ARK Benefit S402 черный","categoryName":"Мобильные телефоны","brandName":"ARK"}\'' j = re.match('.*data-params=\'(.*)\'', s).group(1) 

And then convert the string to a dictionary using the ast library

 import ast d = ast.literal_eval(j) 

or json :

 import json d = json.loads(j)
