The API here: https://api.bitfinex.com/v2/tickers?symbols=ALL

does not have any labels and I want to extract all of the tBTCUSD, tLTCUSD etc.. Basically everything without numbers. Normally, i would extract this information if they are labeled so i can do something like:

data['name']

or something like that however this API does not have labels.. how can i get this info with python?

You can do it like this:

import requests

j = requests.get('https://api.bitfinex.com/v2/tickers?symbols=ALL').json()    

mydict = {}

for i in j:
    mydict[i[0]] = i[1:]

Or using dictionary comprehension:

mydict = {i[0]: i[1:] for i in j}

Then access it as:

mydict['tZRXETH']

    There is no need for `j=json.loads(r.text)`. Just call `.json()` on the response. `r = requests.get('https://api.bitfinex.com/v2/tickers?symbols=ALL').json()` – roganjosh May 10 '18 at 08:30

I don't have access to Python right now, but it looks like they're organized in a superarray of several subarrays.

You should be able to extract everything (the superarray) as data, and then do a:

for array in data:
print array[0]

Not sure if this answers your question. Let me know!

Even if it doesn't have labels (or, more specifically, if it's not a JSON object) it's still a perfectly legal piece of JSON, since it's just some arrays contained within a parent array.

Assuming you can already get the text from the api, you can load it as a Python object using json.loads:

import json
data = json.loads(your_data_as_string)

Then, since the labels you want to extract are always in the first position of the arrays, you can store them in a list using a list comprehension:

labels = [x[0] for x in data]

labels will be:

['tBTCUSD', 'tLTCUSD', 'tLTCBTC', 'tETHUSD', 'tETHBTC', 'tETCBTC', ...]
