How to ignore exceptions in python: Python: How to ignore an exception and proceed?

implemented in your code, but I would also look at @matszwecja's answer to understand why this error is occurring.

for url in r["body"]["illusts"]:
    try:
        print(url["url"])
    except KeyError:
        pass

CodePudding user response：

You can use dict.get,

for url in r['body']['illusts']:
    print(url.get('url'))

To filter out the None values. You can use filter

list(filter(None, [url.get('url') for url in r['body']['illusts']]))
