Use function output as input to another function

Question

My question exactly is i want to use function output as input to another function,

Like:

def first(one,two):
    #some codes gives me info from json files
    api_data = json.loads(api.text)
    return api_data["response"]["info"][one][two];

def second(moreinfo):
    #this code is using first function and gives me the result to do something else on it, beside i want the first function as it is, because i'm using it in the project.
    api_data = json.loads(api.text)
    return api_data[moreinfo]["data"]["name"];

I'm using this in the file to get the result from second function

second(""+str(first(one,"two"))+"")

And i got this error

return api_data[first(one,"two")]["data"]["name"]
KeyError: 'data'

I think this error because first(one,"two") in second function doesn't took, because i tried to put

return api_data["1"]["data"]["name"]

And its work with giving me info for number 1 result from first function,

Thanks and Regards :)

EDITED

Some examples for json

(for first function)

{
    "response": {
        "info": [
            {
                "id": 1,
                "desc": "desc"
            }
        ]
    }
}

Second example (i want to print this in second function)

{
  "1": {
    "data": {
      "name": "Name"
    }
  }
}

Can you print api_data?

There are two approaches that either change the code as per your json response or change the json response on the basis of your code.

1st approach:

def first(index):
    return api_data["response"]["info"][index]['id']

def second(moreinfo):
    return api_data[moreinfo]["data"]["name"]

JSON:

api_data = {'1': {'data': {'name': 'name'}}, 'response': {'info': [{"id": 1, "name": "name"}]}}

Function Call:

second(""+str(first(0))+"")

2nd approach: Based on your given code JSON should be like this.

api_data = {'1': {'data': {'name': 'name'}}, 'response': {'info': {'one': {'two': 1}}}}

Function Call:

second(""+str(first('one', 'two'))+"")

Thanks for your reply but doesn't help me, and My first function take 2 variable, because giving 2 deferent output from it,

Sadia Arif Over a year ago

But it is not possible to get value of key "one" from json because your json does not have key of 'one' or 'two'.

Mohammed Alhanafi Over a year ago

No JSON have what i want, and as said before, when tried to put number str(first('one', 'two')) its get all info i want from number i put.

Sadia Arif Over a year ago

But how would you get a value against 'one' or 'two' key if you are not giving it in json? key must be defined in json.

Mohammed Alhanafi Over a year ago

if you was saying about this, str(first('one', 'two')) one is id of what i want to get and two is what i want to get (ID or Name), str(first(1, "name")) this code print the name of what i want.

The problem when i use PyQt, but if i just try the code without PyQt its work fine so, the question is no longer not solved.

def first(one,two):
    api = requests.get("url")
    api_data = json.loads(api.text)
    return api_data["response"]["info"][one][two]

def second(id):
    api = requests.get("another-url")
    api_data = json.loads(api.text)
    return api_data[id]["data"]["name"]

print(second(str(first("1","id"))))
