So I am creating a react app in which one of the functionalities is to show and present the stock data of a few selected stocks(which I will be giving as an input) , for that I created a flask api in python (I know public api’s are available but I would like to do the task myself) . Since I am new to flask , was just wondering
What will be a efficient way to fetch data from a site (I have one in mind) which can get me the data and then I will push it to my api .
I have some knowledge on python html parse and selenium would these be good ?

for reference my api looks like this:

{
        'MTAR':{
            "Name":"MTAR Technologies",
            "Sector":"Machinery and Aerospace",
            "Current_price":1932.15
        },
        'FORT':{
            "Name": "Fortis Healthcare",
            "Sector": "Health and equipment",
            "Current_price": 466.65
        }
    }

All sorts of suggestions are welcome.
