I need to get from this entire text all the links that come after the 'type': 'r', 'url': (there are 2 of them here). The question is how to implement it?

  • The code lacks closing elements. - Enikeyschik
  • Corrected. Now everything seems to be there. - user311842
  • for x in словарь['attachments'] and inside for size in x['sizes'] plus minor additional checks - andreymal
  • Gives an error KeyError: 'sizes' - user311842
  • It was sealed up x['photo']['sizes'] . Although you have to understand all this yourself if you have read at least one python tutorial - andreymal

This is without checks, and, probably, you will need to do them:

 rs = { 'date': 1539251604, 'from_id': 511076166, ... } for attachment in rs['attachments']: for img in attachment['photo']['sizes']: if img['type'] != 'r': continue print(img['url'])
