but the output of this looks like   `"account": "\"123456789012\""` how do I remove the leading and trailing` \"`

Answer

Is it possible for you to share the event you are using to test?

I used the below event to test:

{
  "detail": {
    "eventVersion": "1.05",
    "userIdentity": {
      "type": "IAMUser",
      "principalId": "AIDAJDPLRKLG7UEXAMPLE",
      "arn": "arn:aws:iam::123456789012:user/Mary_Major",
      "accountId": "123456789012",
      "accessKeyId": "AKIAIOSFODNN7EXAMPLE",
      "userName": "Mary_Major",
      "sessionContext": {
        "sessionIssuer": {},
        "webIdFederationData": {},
        "attributes": {
          "mfaAuthenticated": "false",
          "creationDate": "2019-06-18T22:28:31Z"
        }
      },
      "invokedBy": "signin.amazonaws.com"
    },
    "eventTime": "2019-06-19T00:18:31Z",
    "eventSource": "cloudtrail.amazonaws.com",
    "eventName": "StartLogging",
    "awsRegion": "us-east-2",
    "sourceIPAddress": "203.0.113.64",
    "userAgent": "signin.amazonaws.com",
    "requestParameters": {
      "name": "arn:aws:cloudtrail:us-east-2:123456789012:trail/My-First-Trail"
    },
    "responseElements": null,
    "requestID": "ddf5140f-EXAMPLE",
    "eventID": "7116c6a1-EXAMPLE",
    "readOnly": false,
    "eventType": "AwsApiCall",
    "recipientAccountId": "123456789012"
  },
  "someotherfield": "foo",
  "yetanotherfield": "bar"
}

And my code is:
  print('$$$$$$$$$$$$$$$$$')
  body = event['detail']['userIdentity']['accountId']
  print(body)
  print('$$$$$$$$$$$$$$$$$')

And the response I got from the lambda is
Function Logs
START RequestId: 3263d9d6-e0f0-4378-ae7e-f3c100883bd6 Version: $LATEST
$$$$$$$$$$$$$$$$$
123456789012
$$$$$$$$$$$$$$$$$
END RequestId: 3263d9d6-e0f0-4378-ae7e-f3c100883bd6
