How to Track Absence of Key Value Pairs in a Python Dictionary Using Ternary Conditional

I am receiving two types of dictionary from requesters. some of them has an specific key called portal and some of the no like:

data = {"Other_Key":"Other_Value","portal": {"isHosted": False,"portalServer": [        {"type": "PHP","itemID": "hshshdkdkd"        },        {"type": "ASP","itemID": "5s55s5s5s"        }    ]},"Other_Key":"Other_Value"}

or in another format, simply like like this:

data = {"Other_Key_1":"Other_Value","Other_Key_3":"Other_Value"}

Now I want to grab the value of Portal so I used this ternary one line solution to check the existing of Portal in dictionary

status = data['portal']['isHosted'] if data['portal'] != "" else "NA"print(status)

this is working fine as long as there is a portal node in the data but when is not contain the portal I am getting this error:

Traceback (most recent call last):File "main.py", line 5, in status = data['portal']['isHosted'] if data['portal'] != "" else "NA"KeyError: 'portal'
