Python & Yelp API: how to bypass JSON response LOCATION_NOT_FOUND

Question

I arrive to retrieve JSON from Yelp API. Problems arrive when I search for a town but that town is not in Yelp database. In this case I receive a response:

{
  "error": {
    "code": "LOCATION_NOT_FOUND",
    "description": "Could not execute search, try specifying a more exact location."
  }
}

As I'm searching in bulk I would like to write a statement that says that if "LOCATION_NOT_FOUND" is inside my JSON response, do nothing and pass to the next town.

I need something like this:

if response_data['error']['code'] == 'LOCATION_NOT_FOUND':
    pass
else:

but is not working because it says:

if response_data['error']['code'] == 'LOCATION_NOT_FOUND':
KeyError: 'error'

this because error is not always there but just when there is no town

You need to first check if there is an error. This can be done using the key in dict syntax.

if 'error' in response_data:  # Check if there is a key called "error"
    if response_data['error'].get('code') != 'LOCATION_NOT_FOUND':
        # A different code, should probably log this.
        logging.error(json.dumps(response_data))
else:
    # Continue as normal.
