YahooScraper

This program will take data from any website that you pass into the get_data function. Currently V2.0, I am just getting data from yahoo finance.

I). Understanding the parameters of scraper.get_data: 1). The stock name, or t, has to be passed to this funciton

2). base_url and web_attrs must be passed if you are doing anything
    outside of getting the historical data.
        
3). If you want to get data from financial pages on your url then
    set the pages kw to your dictionary.
        
4). If you want to get the historical data you must pass in the 
    data_source=..., and start=... kw.
    
5). If you want to get the current price then you must pass in the 
    frequency=int, and interval=int kw. Then this program will make 
    x calls to get the price every y seconds (x = interval, y = frequency)

II). Understanding the global variables in main.py:

The web_attributes and base_url dont't change in this program
Yahoo finance uses '?p=' in every url request 
Therefore each page only differs in the stock name and the financial key.
e.x
    This will get the summary for AAPL
        https://finance.yahoo.com/quote/AAPL?p=AAPL

    This will get the balance sheet for AAPL
        https://finance.yahoo.com/quote/AAPL/balance-sheet?p=AAPL

III). Understanding the financial_data dictionary: This dictionary will map a stocks name to another dictionary That dictionary maps the name of a dataframe then that DF e.x financial_data = {'AAPL' : {'Income' : pd.DataFrame, 'Balance' : pd.DataFrame, 'Cash' : pd.DataFrame, 'Historic' : pd.DataFrame, 'Key Stats': pd.DataFrame, 'Summary' : pd.DataFrame, 'Price' : pd.DataFrame}}

IV). Understanding the pages dictionary: pages is a dictionary that maps the user level name to the actual name of The page containing that data. When you pass this into get_data it will Iterate through each page and get the data for that based on the base_url And web attributes
