I am trying to retrieve the titles of multiple items that have been under a single order. There can be multiple subsections under the 'line_items' where the information of each item is displayed, title being one of the parameters for every item.

[0] brings me the first item title.

[-1] brings me the last item title.

How do I interact with the subsections in between? Is there a way to return all associated order titles whether there's 1 or more?

  r = requests.get("jsonURL", params="jsonparams")
  data = r.json()

  for item in data['orders']:
    purchased = item['line_items'][0]['title']
    purchased1 = item['line_items'][-1]['title']

You can do this by adding an inner loop like this:

r = requests.get("jsonURL", params="jsonparams")
data = r.json()

for items in data['orders']:
    for item in items['line_items']:
       print(item['title'])

This will print out the titles of the items in each of the orders.

If you only want to print out a subset of the items you can use a slice on the items['line_items']. If you want to print only the first n items, then you would write items['line_items'][:n]. If you want to print only the last n items, you would write items['line_items'][-n]. You can even combine the two, for instance items['line_items'][1:-2] will skip the first and last two items in the list.

So let’s start to learn how to pretty print JSON data in python. I have already uploaded a tutorial of reading JSON data. You can check Python Read JSON File – Reading JSON in Python . Python JSON Pretty Print Tutorial – Getting Started

Hope this helps for you.

r = requests.get("jsonURL", params="jsonparams")
data = r.json()

result = [items['items'] for items in data['orders']['line_items']]

If you want to get the first index:

print(result[0])

If you want to get the first index:

print(result[-1])

Python JSON: Read, Write, Parse JSON (With Examples), It's common to transmit and receive data between a server and web application in JSON format. In Python, JSON exists as a string. For example: p = '{"name":� Decode a JSON document from s (a str beginning with a JSON document) and return a 2-tuple of the Python representation and the index in s where the document ended. This can be used to decode a JSON document from a string that may have extraneous data at the end. class json.

The JSON from your code will look somewhat like this:

    data =  {
        "orders": {
        "line_items": [
            {
                "title": "abc"
            },
            {
                "title": "def"
            },
            {
                "title": "ghi"
            },
            {
                "title": "jkl"
            },
            {
                "title": "mno"
            }
        ]
    }
}

So, in order to get titles for all items, loop through each item in the line_items list, look for the 'title' key and append its values to an empty list called purchased:

purchased = []
for item in data['orders']['line_items']:
    if 'title' in item.keys():
        purchased.append(item['title'])
print(purchased)
#Output:
['abc', 'def', 'ghi', 'jkl', 'mno']

If you also want the quantity of each item purchased, you can use Counter:

from collections import Counter
print(Counter(purchased))
#Output:
Counter({'abc': 1, 'def': 1, 'ghi': 1, 'jkl': 1, 'mno': 1})

json — JSON encoder and decoder — Python 3.8.5 documentation, This module's encoders and decoders preserve input and output order by default. Order is only lost if the underlying containers are unordered. Prior to Python 3.7,� JSON in Python. Python has a built-in package called json, which can be used to work with JSON data.

Working with JSON in Python, There are several different solutions to working with JSON in Python, Navigate to where you want to run the example code, create a file It turns the JSON output into a Response object with the application/json mimetype. Before starting the details of parsing data, We should know about ‘json’ module in Python. It provides an API that is similar to pickle for converting in-memory objects in Python to a serialized representation as well as makes it easy to parse JSON data and files.

  • You need a loop and some data structure to store the results (probably a list). The explanation of both is way beyond the scope of this site.
  • If you can provide an example of what the data looks like, I can try to write something up
