How to search for Keywords in JSON

Question

i am using python json and i want to let my Python code search for specefic Keywords in a JSON-File.

Basically it should search for the "profilename" and then go one line down and print the email of the profile out.

[
  {
    "profilename": "Test123"
    "email": "[email protected]",
    "phone": "+1 (983) 443-3504",
    "address": "359 Rapelye Street, Holtville, Marshall Islands, 9692"
  },
  {
    "profilename": "QTest123"
    "email": "[email protected]",
    "phone": "+1 (831) 563-3240",
    "address": "525 Allen Avenue, Iola, Kentucky, 894"
  }
]

Like the code should search for profilename "Test123" and print out the email of that, like going one line down and print the email out.

I tried many things but i didnt even come one step closer, so sharing my current code would help 0 :/

Thanks.

Answer 1

If I understand you correctly, you are trying to find a profile by the field profilename and return the user’s email.

profiles = [
    {
        "profilename": "Test123",
        "email": "[email protected]",
        "phone": "+1 (983) 443-3504",
        "address": "359 Rapelye Street, Holtville, Marshall Islands, 9692",
    },
    {
        "profilename": "QTest123",
        "email": "[email protected]",
        "phone": "+1 (831) 563-3240",
        "address": "525 Allen Avenue, Iola, Kentucky, 894",
    },
]


def get_profile_email(profilename):
    profile = next(
        (item for item in profiles if item["profilename"] == profilename), None
    )
    if profile:
        return profile["email"]
    return None

print(get_profile_email("Test123"))

Output:
[email protected]

To load the profiles from a file:

import json

with open("profiles.json", "r") as f:
    profiles = json.loads(f.read())

Deserialize the data into a python object (list of dictionaries in this case):

import json

json_str = '''[
  {
    "profilename": "Test123",
    "email": "[email protected]",
    "phone": "+1 (983) 443-3504",
    "address": "359 Rapelye Street, Holtville, Marshall Islands, 9692"
  },
  {
    "profilename": "QTest123",
    "email": "[email protected]",
    "phone": "+1 (831) 563-3240",
    "address": "525 Allen Avenue, Iola, Kentucky, 894"
  }
]'''

list_of_dicts = json.loads(json_str)

Then find and print out your entry:

profile_entry = next(el for el in list_of_dicts if el['profilename'] == 'Test123')
print(profile_entry['email'])

StopIteration occurs when you have not profilename == Test123 in your data. More about the list of dictionaries search here.

    "email": "[email protected]",
    "phone": "+1 (983) 443-3504",
    "address": "359 Rapelye Street, Holtville, Marshall Islands, 9692"
  },
  {
    "profilename": "QTest123",
    "email": "[email protected]",
    "phone": "+1 (831) 563-3240",
    "address": "525 Allen Avenue, Iola, Kentucky, 894"
  }
]
profile_name =  "Test123"
data = [x for x in json if x['profilename'] in profile_name]
print(data[0]['email'])
>>>[email protected]
