How do we make an exception in the cycle, continue the violin?

[irl]

Tell me how to do the exclusion cycle. Example:

user_json = json.loads(req.text)
for acc in user_json['result']['per']:

try:

if user_json['result']['per'] is not None:

account.append(str(acc['name']))

else:

account.append("mail.ru")

except:

account.append("mail.ru")

Such decisions do not work because if there is no result in requests in json, the crypt falls

    for acc in user_json['result']['per']:

KeyError: 'result'

And I need to have if it wasn't even important, he added a default value in this case mail.ru

p.s. sometimes iterations don't add value, the things that result, they're gone, so at this point the violin falls, and I need to keep it going.

One line:

account = [acc.get('name', "mail.ru") for acc in (user_json['result']['per'] if 'result' in user_json and 'per' in user_json['result'] else [{}])]
