Default dict keys to avoid KeyError

I parsed some JSON data, creating bb_json, and am trying to write CSV data based on it to csv_writer. I have this code:

for product in bb_json['products']:
    row = []

    row.append(product['sku'])
    if product['name']:
        row.append(product['name'])
    else:
        row.append("")
    if product['description']:
        row.append(product['description'])
    else:
        row.append("none")
    row.append(product['image'] + " ")
    if product['manufacturer']:
        row.append(product['manufacturer'])
    else:
        row.append("UNKNOWN")
    row.append(product['upc'])
    row.append(product['department'])
    row.append(product['class'])
    row.append(product['subclass'])
    
    csv_writer.writerow(row)    

But I get a KeyError from the attempts to read data from product, because many of these values are unpopulated. How can I fill in default values in the row?

You can use your_dict.get(key, "default value") instead of directly referencing a key.
