[Solved] defaultdict key default value issues

by


I am guessing, that the defaultdict is not what you want to use.

Default values should be declared in the second argument of the get method.

problem = [{'lastInspection': {'date': '2018-01-03'}, 'contacts': []}]
default_inspection = { 'date': '2018-01-03' }

for p in problem:
    # default_inspection is returned, when 'lastInspection' is not present in the json
    inspection = p.get("lastInspection", default_inspection)
    print(inspection)
    # now you access date, as you are sure, that it is present
    print(inspection['date'])
