Python3 for loop over a dict

Question

I am trying to get all the values individually for each asset (BCHUSD and TRXUSD).

What I want to do is something like this:

BCHUSD a = 301.340000 b = 301.160000 c = 301.280000



TRXUSD a = 0.0609450 b = 0.0609440 c = 0.0609540 

Could someone tell me how I can do it please?

Regards!

import requests
import json



while True:    
    req = requests.get('https://api.kraken.com/0/public/Ticker?pair=BCHUSD,TRXUSD,XRPUSD')
    
    print(req)
    
    <Response [200]>
    
    print(type(req))
    
    <class 'requests.models.Response'>
    
    obj = req.json()
    
    print(type(obj))
    
    <class 'dict'>
    
        
    for k, v in obj.items():
        if type(v) is dict and k:
            for nk, nv in v.items():
                print(nk, nv)

Answer 1

I think the following could help you as a starting point:

response_json = {
    "title": "name",
    "abc": {'a': [1,2,3], "b": [2,3,4]},
    "ohter_stuff": "xxx",
    "xyz": {'a': [10, 20 ,30], "b": [20, 30, 40]}
}

# select relevant key value pairs
data = {
    key: value for key, value in response_json.items() 
    if isinstance(value, dict)
}

# get the inner subdict index length
length = len(data['abc']['a'])
# get the inner subdict keys
items = list(data['abc'].keys())

# loop and print
for index in range(length):
    for name, subdict in data.items():
        # join the items at index pairs into a string
        index_items = " ".join(
            f"{item} = {subdict[item][index]}" 
            for item in items
        )
        print(name, index_items)

This is a pure standard library python solution. If you can install other libraries, I would recommend to have a look into pandas.
