If python doesn't find certain value inside JSON, append something inside list

Question

I’m making a script with Python to search for competitors with a Google API.

Just for you to see how it works:

First I make a request and save data inside a Json:

    # make the http GET request to Scale SERP
    api_result = requests.get('https://api.scaleserp.com/search', params)

    # Save data inside Json
    dados = api_result.json()

Then a create some lists to get position, title, domain and things like that, then I create a loop for to append the position from my competitors inside my lists:

# Create the lists
    sPositions = []
    sDomains = []
    sUrls = []
    sTitles = []
    sDescription = []
    sType = []

    # Create loop for to look for information about competitors
    for sCompetitors in dados['organic_results']:
        sPositions.append(sCompetitors['position'])
        sDomains.append(sCompetitors['domain'])
        sUrls.append(sCompetitors['link'])
        sTitles.append(sCompetitors['title'])
        sDescription.append(sCompetitors['snippet'])
        sType.append(sCompetitors['type'])

The problem is that not every bracket of my Json is going to have the same values. Some of them won’t have the "domain" value. So I need something like "when there is no ‘domain’ value, append ‘no domain’ to sDomains list.

I’m glad if anyone could help.

Thanks!!

you should use the get method for dicts so you can set a default value incase the key doesn’t exist:

for sCompetitors in dados['organic_results']:
    sPositions.append(sCompetitors.get('position', 'no position'))
    sDomains.append(sCompetitors.get('domain', 'no domain'))
    sUrls.append(sCompetitors.get('link', 'no link'))
    sTitles.append(sCompetitors.get('title', 'no title'))
    sDescription.append(sCompetitors.get('snippet', 'no snippet'))
    sType.append(sCompetitors.get('type', 'no type'))
