How to convert a single item list to a dictionary?-CodePudding

symbol = 'AAPL'
api_url = f'https://financialmodelingprep.com/api/v3/profile/{symbol}?apikey={FMP_API_TOKEN}'
data = requests.get(api_url).json()
data

I called this api in a Jupyter notebook and the json I received was a single item list that looked like the following:

I know it will be easier for me to finish my project if the json I receive is a dictionary instead of a list. How can I convert this list to a dictionary or just have a dictionary print every time I call the api?

CodePudding user response：

If it is always a one-item list then just call the first element in the list to get the dictionary.

data = requests.get(api_url).json()[0]

CodePudding user response：

The robust way to handle this is to create a function that handles a single dictionary:

def response_handler(data: dict):
    # Do what you need to do

Then, when you get your list response, simply call the handler on each dictionary:

for data in response:
    response_handler(data)

That said, if you only ever need the first element, per the other responses, then you just need to requests.get(api_url).json()[0] to grab the first element. Note that you're getting a list of dictionaries - and you're only interested in a dictionary. So if the first element of that list is the dictionary you care about, you can just index into the list you have (the [0] subscript).
