How to Find a Specific Field Value from a JSON list in Python

To find a specific field value from a JSON list in Python, you can iterate through the list of JSON objects and access the desired field in each object.

Here's an example of finding the price of a laptop with the name "samsung" in the list, and then printing it:

json_list = [
    {
        "laptop_name": "dell",
        "price": 500
    },
    {
        "laptop_name": "acer",
        "price": 400
    },
    {
        "laptop_name": "samsung",
        "price": 600
    }
]


def find_price_from_json_list(json_list, laptop_name):
    for dict in json_list:
        if dict['laptop_name'] == laptop_name:
            return dict['price']

#Calling method
price = find_price_from_json_list(json_list,'samsung')
print(price)

The output of the above code is as follows:

600

Using Python List comprehension to get the price of a specific laptop name:

json_list = [
    {
        "laptop_name": "dell",
        "price": 500
    },
    {
        "laptop_name": "acer",
        "price": 400
    },
    {
        "laptop_name": "samsung",
        "price": 600
    }
]


def find_price(json_list, laptop_name):
    return [p for p in json_list if p['laptop_name']==laptop_name][0]['price']

#Calling method
price = find_price(json_list,"samsung")
print(price)

Output:

600
