Hey! this parser from a scrapper gives me an error:

Traceback (most recent call last):
  File "/Users/jakubstrawa/programming/deorwork/ecommerce/scrapper/woocommercescrapper.py", line 112, in <module>

    parsed_categories.append(d[str(category['id'])])
KeyError: '523'

I've never encountered KeyError 523 and can't find it anywhere on the internet. Do you have any idea whats wrong? Thanks in advance for your help

Your dictionary `d` doesn't have a key `'523'`. `category['id']` was 523 for some item, and you haven't handled the case where the id is not in the dict. — shriakhilc, Jan 04 '22 at 11:43

error means there is no key "523" in dictrionary d as shown

 d = {
            '158': '2',
            '533': '4',
            '156': '5',
            '379': '6',
            '277': '7',
            '443': '8',
            '528': '20',
            '295': '21',
            '306': '22',
        }

you can use try except block to catch exception

better to check with an `in` instead of catching an exception that you can easily prevent. – luk2302 Jan 04 '22 at 11:45
