The FMP API offers different types of data ranging from stock prices and historical data to financial statements and market performance. The complete API documentation is available here. This API is perfect for someone who loves to dabble with financial data as a hobby and incorporate it into other projects. I have no affiliation with FinancialModelingPrep and its web API development.

Answered 2021-Jun-15 at 11:26So if the key for os.getenv()
is invalid, it returns the default values that you pass as the second parameter. If you don't set this default value, it returns a None

Jupyter Notebook. A Batch API call returns a JSON array of objects. Parsing requires for loops (weird). I need to append certain JSON object info into a Pandas DataFrame.

QUESTION
I'm working on a small stock app that displays stock based on the price the user selected. Initially when the app loads I display all the stocks. However, I implemented a filter, when the user taps on a text field it segues to a second view controller and the user have to select the price they want by selecting a radio button. I've successfully passed the user input back using protocols and delegate and saving it to a priceTarget variable, However, I'm not sure how to update the UI with the new price. I'm assuming I have to reload my tableView and fetch the data again with the updated price. Can someone offer a few suggestions?
...ANSWER
Answered 2021-Jun-02 at 22:53Your thought process is correct. When the user taps the button and the delegate calls passPrice(price:)
, simply call fetchData()
at the end of that task.
Keep in mind that the cells the table view has on screen when the button is tapped is specifically rendering what's in stockArray
. Therefore, be careful when you modify stockArray
because if the new data fetch results in an array of a different size or the parsing of results is relatively time consuming all while the user is actively scrolling through the table view, it could have unwanted side effects such as curiously-rendered cells or even a fatal out-of-bounds error which would crash the app. Therefore, I would suggest creating a local array (local to the scope of the closure) within the data return that you populate with results that you then hand off to stockArray
before reloading the table view:

QUESTION
I want to design an ApiFetcher in order to prevent duplicate code.
How to I pass a custom child component to my ApiFetcher so that it renders the content I specify in the custom component instead of a hard coded element in the return statement?
I want to keep the logic of the ApiFetcher and the CompanyProfile components out of their parent components.
...ANSWER
Answered 2021-Apr-03 at 14:07You can maybe use props.children
in order to move rendering logic to Parent component. Here's how I will strucutre the component:
QUESTION
I'm trying to implement an API fetcher as a reusable component in order to reduce duplicate code.
How do I pass a child component to this ApiFetcher so that it renders the specific child instead of a hard coded component?
Besides, is my CompanyProfile component coded in an effective way or is there room for optimisation?
...ANSWER
Answered 2021-Apr-03 at 11:01You can use a higher-order component.
A higher-order component (HOC) is an advanced technique in React for reusing component logic. HOCs are not part of the React API, per se. They are a pattern that emerges from React’s compositional nature.
Example:
QUESTION
I'm trying to take all the json data that are returning and add its content to a collection view, where the content for each index position is added to its own cell in the collection, However, only 1 cell is being created which is the first index in the array.
This is what it looks like right now
This where I'm performing the request to get the data
...ANSWER
Answered 2021-Mar-30 at 22:37You're over-writing the sectorName
and performance
label each time in this loop. Thus, the labels only show the last values in sectorPayload
.
QUESTION
I have below code that reads from a csv file a number of ticker symbols into a dataframe.
Each ticker calls the Web Api returning a dafaframe df which is then attached to the last one until complete.
The code works , but when a large number of tickers is used the code slows down tremendously.
I understand I can use multiprocessing and threads to speed up my code but dont know where to start and what would be the most suited in my particular case.
What code should I use to get my data into a combined daframe in the fastest possible manner?
...ANSWER
Answered 2021-Mar-18 at 21:01First optimization is to avoid concatenate your dataframe at each iteration.
You can try something like that:

I am extracting data from this API I was able to save the JSON file on my local machine. I want to run the requests for several stocks. How do I do it? I tried to play with for loops but not good came out of this. I attached the code below. the out put is:
...ANSWER
Answered 2021-Mar-12 at 10:07Querying multiple APIs iterativelly will take a lot of time. Consider using theading
or AsyncIO
to do requests simultaniously and speed up the process.
In a nutshell you should do something like this for each API:
