I have a JSON file like this; { "name" : "maria", "age" : "40", "adress" : "usa" }
and I want to apply a function which takes as arguments the name, age, address
my basic function is like this:
def get(name, age, address):
print(name has (age) years old and a house in (address)
the question is how to feed the function from the JSON file
For this simple test.json JSON file:
{ "name" : "maria", "age" : "40", "address" : "usa" }
We can deserialize the JSON into a dictionary with json.load, then pass the name, age and address values to the get() function:
from json import load
def get(name, age, address):
print(f"{name} has {age} years old and a house in {address}")
with open("test.json") as f:
data = load(f)
get(data["name"], data["age"], data["address"])
I used Formatted string literals to insert the name, age and address into a formatted string. These are also known as f-strings.
It might also be safer to use dict.get() to fetch the values and give a default value of None, since you could get a KeyError if the key doesn't exist. You can also specify any other default value.
get(data.get("name"), data.get("age"), data.get("address"))
Output:
maria has 40 years old and a house in usa
