How to filter and print particular json dictionaries in python

I’m in the process of learning python. I encountered a problem with json that I can’t overcome.

I have this dataset from json in python:

{
    "Sophos": {
        "detected": true,
        "result": "phishing site"
    },
    "Phishtank": {
        "detected": false,
        "result": "clean site"
    },
    "CyberCrime": {
        "detected": false,
        "result": "clean site"
    },
    "Spam404": {
        "detected": false,
        "result": "clean site"
    },
    "SecureBrain": {
        "detected": false,
        "result": "clean site"
    },
    "Hoplite Industries": {
        "detected": false,
        "result": "clean site"
    },
    "CRDF": {
        "detected": false,
        "result": "clean site"
    },
    "Rising": {
        "detected": false,
        "result": "clean site"
    },
    "Fortinet": {
        "detected": true,
        "result": "phishing site"
    },
    "alphaMountain.ai": {
        "detected": true,
        "result": "phishing site"
    },
    "Lionic": {
        "detected": false,
        "result": "clean site"
    },
    "Cyble": {
        "detected": false,
        "result": "clean site"
    }
}

I would like to filter these dictionaries in such a way as to print only those keys and values in which "detected": true.

For example I would like print only

{
    "Sophos": {
        "detected": true,
        "result": "phishing site"
    },
    "Fortinet": {
        "detected": true,
        "result": "phishing site"
    }
}

I use VirusTotal apikey v2 https://developers.virustotal.com/v2.0/reference/domain-report
My code in python:

parameters = {'apikey': api_key, 'resource': domain}

response = requests.get(url, params=parameters)
    
python_response = json.loads(response.text)

scans = python_response["scans"]

example = json.dumps(python_response["scans"], indent=4)

print(example)

I’m looking for a simple and readable way to do it so that I understand it as best I can. I would like print result in Python. I searched and read various solutions for this (list comprehension or filter() with lambda), but it did not help me.

I’m still learning, thanks in advance for your understanding if it’s a simple case.

Thank you in advance for your help and answers.

>Solution :

You can use dict comprehension to filter the response dictionary.
Note that in the example you provided, I think you have json data and not the python object. true is not a valid boolean keyword in python, it should’ve been True instead.

filtered = {k: v for k, v in orignal_dict.items() if v.get("detected") == true}

For your example –

true = True
false = False

data = {
    "Sophos": {
        "detected": true,
        "result": "phishing site"
    },
    "Phishtank": {
        "detected": false,
        "result": "clean site"
    },
    "CyberCrime": {
        "detected": false,
        "result": "clean site"
    },
    "Spam404": {
        "detected": false,
        "result": "clean site"
    },
    "SecureBrain": {
        "detected": false,
        "result": "clean site"
    },
    "Hoplite Industries": {
        "detected": false,
        "result": "clean site"
    },
    "CRDF": {
        "detected": false,
        "result": "clean site"
    },
    "Rising": {
        "detected": false,
        "result": "clean site"
    },
    "Fortinet": {
        "detected": true,
        "result": "phishing site"
    },
    "alphaMountain.ai": {
        "detected": true,
        "result": "phishing site"
    },
    "Lionic": {
        "detected": false,
        "result": "clean site"
    },
    "Cyble": {
        "detected": false,
        "result": "clean site"
    }
}


filtered = {k: v for k, v in data.items() if v.get("detected") == true}
print(json.dumps(filtered, indent=4))

Output:

{
    "Sophos": {
        "detected": true,
        "result": "phishing site"
    },
    "Fortinet": {
        "detected": true,
        "result": "phishing site"
    },
    "alphaMountain.ai": {
        "detected": true,
        "result": "phishing site"
    }
}
