Filtering out if the dictionary list has the key in a set

events=[
    {'creator': {'email': 'a@hotmail.com', 'self': True}, 'organizer': {'email': 'a@hotmail.com', 'self': True}, 'start': {'dateTime': '2022-03-15T07:00:00-0700', 'timeZone': 'America/Vancouver'}, 'end': {'dateTime': '2022-03-15T07:30:00-0700', 'timeZone': 'America/Vancouver'},  'attendees': [{'email': 'b@hotmail.com', 'responseStatus': 'needsAction'}, {'email': 'a@hotmail.com', 'organizer': True, 'self': True, 'responseStatus': 'needsAction'}]},
    {'creator': {'email': 'a@hotmail.com', 'self': True}, 'organizer': {'email': 'a@hotmail.com', 'self': True}, 'start': {'dateTime': '2022-03-15T07:30:00-0700', 'timeZone': 'America/Vancouver'}, 'end': {'dateTime': '2022-03-15T08:00:00-0700', 'timeZone': 'America/Vancouver'}, 'attendees': [{'email': 'b@hotmail.com', 'responseStatus': 'needsAction'}, {'email': 'a@hotmail.com', 'organizer': True, 'self': True, 'responseStatus': 'needsAction'}]},
    {'creator': {'email': 'a@hotmail.com', 'self': True}, 'organizer': {'email': 'a@hotmail.com', 'self': True}, 'start': {'dateTime': '2022-03-17T00:00:00-0700', 'timeZone': 'America/Vancouver'}, 'end': {'dateTime': '2022-03-17T00:30:00-0700', 'timeZone': 'America/Vancouver'}}
]
   

I would like to filter a dictionary list(slightly different list structure) if it has an [‘attendee’][’email’] that is valid(in emails) which is not the organizer. So [‘attendees’][‘organizer’] can’t be the one used.

emails=['b@hotmail.com'] 
for e in events:
    if e['attendees']['email'] in emails:
        print(e)

Produces

TypeError at /
list indices must be integers or slices, not str

Should Output:

>Solution :

e[‘attendees’] is a list so you need to specify it’s index

for e in events:
    try:
        if e['attendees'][0]['email'] in emails:
            print(e)
    except KeyError:
        pass
