Data Evaluation with Python

When receiving data from a server, you are right that using a for loop would cause a list error. However, there are several ways to evaluate and process data more robustly.

Here is an example of how to parse and return specific data from a JSON response using Python:

Assuming a JSON response

[
{
"id": 1,
"name": "John Doe",
"age": 30,
"city": "New York"
},
{
"id": 2,
"name": "Jane Smith",
"age": 25,
"city": "Los Angeles"
}
]

Using Python to parse and return data

import json









Assuming the JSON response is stored in a variable named 'data'
data = [
{"id": 1, "name": "John Doe", "age": 30, "city": "New York"},
{"id": 2, "name": "Jane Smith", "age": 25, "city": "Los Angeles"}
]

Define a function to extract specific data
def get_data(data):
keys_to_extract = ["id", "name", "age"]
for item in data:
extracted_info = {}
for key in keys_to_extract:
if key in item:
extracted_info[key] = item[key]
yield extracted_info

Example usage
for person in get_data(data):
print(person)

In this example, we define a function get_data that takes a list of objects (data) and returns a generator expression that produces dictionaries containing specific data (e.g., id, name, and age). We then use an example usage section to demonstrate how to iterate over the extracted data.

Accessing Specific Data

To access specific data, you can simply loop through the generator expression:

for person in get_data(data):
print(person["id"]) 
print: 1
print(person["name"]) 
print: John Doe

Alternatively, if you want to use a for loop instead of a generator expression, you can define a separate function that takes the data as an argument:

def get_person(person):
return {"id": person["id"], "name": person["name"]}

Example usage
data = [
{"id": 1, "name": "John Doe", "age": 30, "city": "New York"},
{"id": 2, "name": "Jane Smith", "age": 25, "city": "Los Angeles"}
]
for person in data:
print(get_person(person))

This approach is best suited when working with larger data sets that do not fit in memory.
