python json data in tuple format not parsable - python

I'm having a hard time understanding why the following output, which is supposed to be json format, and is generated from a datbase query, isnt parsable.

I cant treat it like a json because when I do a type(dbresponse) on the data (directly from the database), python tells me its a "tuple" data. But I know in order for me to be able to access the values, python needs to see the data as a dict.
I have tried converting it multiple different ways, all to no avail.
str(dbresponse)
eval(dict(dbresponse))
str(list(dbresponse)) # tried to convert it to a list, then to a str in hopes of then being able to convert it to dictionary. didnt work.
I dont know much about json.
My question is, is there a foolproof way to turn/convert the above data from tuple to dictionary? And once that is done, how do i iterate through all the keys/values in the data so I see what is available.
I tried pprinnt (pretty print) but that isn't so clear to me (i could be using it incorrectly).

If your response really is a string as shown here, and always has the same format, you could remove the ((' at the start and ',),) at the end. The rest is a valid JSON string:

The inner content seems to be wrapped in single quote ', but contains unescaped single quotes (e.g. "MAYO'S"). This of course is a syntax error.
Despite the several levels of escaping seems the code that generated the content still isn't able to get it right.
As Thierry found however removing the first 4 and last 6 characters leaves a valid JSON (in this case) and you can parse it with json.loads(dbresponse[4:-6]).

For support other types of inputs we can use find and rfind:
import json
# dbresponse = ...
begin = dbresponse.find("'")
end = dbresponse.rfind("'")
data = json.loads(dbresponse[begin+1:end])

I am not familiar with gzip.GzipFile format.
Is there a way to make it a dictionary?

You will want to make use of the json module and the gzip module in Python, both of which are part of the Python Standard Library.
The gzip module provides the GzipFile class, as well as the open(),
compress() and decompress() convenience functions. The GzipFile class
reads and writes gzip-format files, automatically compressing or
decompressing the data so that it looks like an ordinary file object.
To read the compressed file, you can call gzip.open().
Opening the file with the default rb mode, will return a gzip.GzipFile object, from which you can obtain a bytes-like object by calling read().
Then, using json.loads(), you can convert the raw data into a usable Python object -- a dictionary.
The snippet below is a simple demonstration of this in action:
import gzip
import json
with gzip.open('gzipped_file.json.gz', 'rb') as f:
raw_json = f.read()
data = json.loads(raw_json)
print(type(data))
# Prints <class 'dict'>
print(data)
# Prints {'originaltitle': 'Leasing Specialist - WPM Real Estate Management', 'workexperience ...
print(data['workexperiences'][0]['company'])
# Prints Home Properties

Which is better considering this situation - using PayPal adaptive payments for parallel payment processing and integration, or using a Braintree merchants account for payment processing and syncing with a 3rd-party for payment integration? Can PayPal adaptive payments do it all?
Suppose you have a business called Sewing Bliss & Co. It has two founders. One founder lives in NYC and creates baby clothing, the other founder lives in CA and creates quilts. They both sell their products through their ecommerce web app called www.sewingbliss.co.
But, they want their income to be organized into two separate streams - whenever a visitor purchases a baby item it goes into the NYC founder's PayPal account. And whenever a quilt is purchased it goes to the CA founder's PayPal account. If a customer purchases both a baby item and a quilt in one transaction, the transaction goes through and is divided up respectively. To the customer, the transaction appears seamless.
I am a web developer (mostly Python/Django). I am curious how this would best be implemented. Any insights?

So I image you would have two different pages, one for the quilt and one for the baby items. Now you could set up individual PayPal buttons for each page in which each button will send money to a different account. I would suggest checking out django-paypal.
The documentation on django-paypal can be a little confusing so read carefully.

I developed a recommender system using Matrix Factorization in Python. The ratings are in the range [1-5]. It works very well. This system is made for client advisors rather than clients themselves. Hence, the system recommends some products to the client advisor and then this one decides which products he's gonna recommend to his client.
In my application I want to have 2 additional buttons: relevant, irrelevant. Thus, for each recommendation the client advisor would press the button irrelevant if the recommendation is not good but its rating is high and he would press the button relevant if the recommendation is good but its rating is low.
The problem is that I can't figure how to update the ratings when one of the buttons is pressed. Please give me some idea about how to handle that feature. I insist on having only two buttons (relevant and irrelevant), the client advisor can't modify the rating himself.
Thank you very much.

Based on your comment above, I would manipulate the Number of times they purchased the product field. You need to basically transform the Number of times they purchased the product field into an implicit rating field. I would maybe scale the product rating system to 1-5. If they press the don't like the product button, the rating is a 1, if they press the like the product button, they get a 5. If they have bought the product frequently, it's a 5, otherwise it starts at a 3 on the first purchase and scales up to a 4 then 5, based on your data. If they have never bought the product AND have never rated the product, it's a null value, so won't contribute to ratings.

I'm trying to integrate balanced payments API into my work. I've looked at Docs and other concerned forums also but didn't get clear my doubts.
I understand the flow of this though, but due to some method names i'm getting confused.
e.g. customer.
https://docs.balancedpayments.com/1.0/overview/getting-started/#charge-a-credit-card
What have I tried till now:(in Python)
I've created a dummy/Test bank and it's working fine.
bank_account = balanced.BankAccount(...) but I dont know how much could I debit from this or first do I have to credit into.
after this I created a card and then I created a customer customer = balanced.Customer().save()
and then associated the card with the customer customer.add_card('/v1/marketplaces/TEST-MP52IlCmywk6hGbgS75QSlN/cards/CC3AiMy0KEP1PhwnffMk32RF')
but how is this statement working?
customer.add_bank_account('/v1/bank_accounts/BA24Zc2jo1moflunJDxKrCrB')
I'm slightly confused with this customer word.
Could somebody please explain this from beginning in simple steps.

Customers are objects that represent businesses or people within your marketplace (i.e. buyers and sellers). In this revision of the API, funding instruments (e.g. credit cards, bank accounts) must be associated to a specific customer object before you can initiate any transactions.
The method you listed:
customer.add_bank_account('/v1/bank_accounts/BA24Zc2jo1moflunJDxKrCrB')
Is associating the bank account to the customer object that you created.
You specify the amount for a debit (charge) or credit (payout). The limit depends on a number of factors (e.g. credit limit, available funds, transaction limits)

Does anyone know if there is an API for Oneworld Alliance ? The idea is to program in Python a Traveling Salesman, who visits all airports in the system based on actual available flight connections.

I don't think Oneworld Alliance themselves, or other airlines or alliances, have their own APIs. Not sure whether asking this is ontopic to SO.
Try the search engines and booking sites: Travelocity, Expedia, Hotwire, cheaptickets...
For example by Google here's Expedia Affiliate Network.
Kayak apparently used to have a beta API but it was pulled due to misuse.
Not sure how easy it is to scrape Oneworld's site or timetables, I wouldn't start there.
Remember the airlines have a negative incentive to allow their data to be scraped, whereas the search engines have a positive incentive (within reasonable limits). So start with the latter.
When you say "based on actual available flight connections", I presume you just check whether airline X has a route connecting city A to city B, not at actual seat inventory on specific dates and times, which seems needless. Do you need durations and frequencies?
Btw, there are 900 hits on SO on "Traveling Salesman", you might be able to reuse someone else's data.
