How to filter out nested elements from a nested dictionary-CodePudding

I have the following list of dictionaries:

messages_all = [{'type': 'message',
      'subtype': 'bot_message',
      'text': "This content can't be displayed.",
      'ts': '1573358255.000100',
      'username': 'Userform',
      'icons': {'image_30': 'www.example.com'},
      'bot_id': 'JOD4K22SJW',
      'blocks': [{'type': 'section',
        'block_id': 'yCKUB',
        'text': {'type': 'mrkdwn',
         'text': 'Your *survey* has a new response.',
         'verbatim': False}},
       {'type': 'section',
        'block_id': '37Mt4',
        'text': {'type': 'mrkdwn',
         'text': '*Thanks for your response. Where did you first hear about us?*\nFriend',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'hqps2',
        'text': {'type': 'mrkdwn',
         'text': '*How would you rate your experience?*\n9',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'rvi',
        'text': {'type': 'mrkdwn', 'text': '*city*\nNew York', 'verbatim': False}},
       {'type': 'section',
        'block_id': 'q=L ',
        'text': {'type': 'mrkdwn',
         'text': '*order_id*\n123456',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'iI6v',
        'text': {'type': 'mrkdwn',
         'text': '*user_id*\n987654',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'qfaZM',
        'text': {'type': 'mrkdwn',
         'text': '*user_name*\nJohn Smith',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'MkFq',
        'text': {'type': 'mrkdwn',
         'text': '*order_id*\n12345',
         'verbatim': False}},
       {'type': 'section',
        'block_id': ' zD',
        'text': {'type': 'mrkdwn', 'text': '*rating*\n9', 'verbatim': False}},
       {'type': 'section',
        'block_id': 'glVN',
        'text': {'type': 'mrkdwn',
         'text': '*office*\nSouth',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'Ox5',
        'text': {'type': 'mrkdwn',
         'text': '*date*\nJuly 1, 2020',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'pOZ',
        'text': {'type': 'mrkdwn',
         'text': '*ord_time*\n5:36PM',
         'verbatim': False}},
       {'type': 'section',
        'block_id': 'e1hbI',
        'text': {'type': 'mrkdwn',
         'text': '*sales*\nJ73',
         'verbatim': False}},
       {'type': 'actions',
        'block_id': '1Ug0A',
        'elements': [{'type': 'button',
          'action_id': '=iuO',
          'text': {'type': 'plain_text', 'text': 'View typeform', 'emoji': True},
          'url': 'www.example.com'}]},
       {'type': 'section',
        'block_id': 'Echk',
        'text': {'type': 'mrkdwn', 'text': ' ', 'verbatim': False}}]},
     {'client_msg_id': '123456jk-a19c-97fe-35c9-3c9f643cae19',
      'type': 'message',
      'text': '<@ABC973RJD>',
      'user': 'UM1927AJG',
      'ts': '1573323860.000300',
      'team': 'B09AJR39A',
      'reactions': [{'name': ' 1', 'users': ['UM1927AJG'], 'count': 1}]}]

I'd like to be able to search through this list and filter out of the following dictionary:

 {'client_msg_id': '123456jk-a19c-97fe-35c9-3c9f643cae19',
  'type': 'message',
  'text': '<@ABC973RJD>',
  'user': 'UM1927AJG',
  'ts': '1573323860.000300',
  'team': 'B09AJR39A',
  'reactions': [{'name': ' 1', 'users': ['UM1927AJG'], 'count': 1}]}

To do so, I have tried the following list comprehension:

filtered = [elem for elem in messages_all if not (elem.get('type') == 'message' and elem.get('subtype') == 'channel_join') 
                     and not (elem.get('type') == 'message' and elem.get('subtype') == 'channel_leave')
                     and not (elem.get('type') == 'message' and elem.get('reply_users_count') == 2)
                     and not (elem.get('type') == 'message' and elem.get('reactions') is not None) ]

Unfortunately, the and not (elem.get('type') == 'message' and elem.get('reactions') is not None is not dropping the dictionary above.

Would someone kindly help me with the syntax?

Thank you.

CodePudding user response：

Since the last dictionary is the only one that has the "client_msg_id" key, you could use:

>>> [m for m in messages_all if not m.get('client_msg_id')]
