write this in Pythom Code.

In this assignment, we will apply lists, tuples, set and $/$ or dictionaries to solve a problem with first$-$class functions.

Imagine this scenario: A company $/$ individual buys $100$ shares of a stock at $$12$ per share, then another $100$ of the

same stock at $$10$ per share, and then sells $150$ shares at $$15.$ After the sale, taxes must be paid $($capital gains tax.

But what is the profit since two different prices were paid for the stock. Well, the IRS has a rule for this situation. It

is an asset$-$management and valuation method in which the assets $($in this case stocks bought first are sold first.

So$,$ we must sell all shares of the first batch for a sale amount of $$300($$$3$ x $100,$ then $50$ of the shares from the

second batch, for a sale amount of $$250($$$5*50,$ yielding a total sale amount of $$550.$ This assumes all the stocks

are from the same company. We made $550$ but we must pay tax at a rate of $15\%.$ So$,$ the tax is $$82\mathrm{.}50$ and the take$-$

home is $$467\mathrm{.}50.$

We will write code to solve this problem. The best solution is one based on classes, but for now we will use our

collections. Later we can revisit this with classes and objects.

For our solution, we will do these calculations for arbitrary purchases and sales of shares of multiple companies.

Specifications

$$ Present the user with a menu of three options:

o Buy $($B or b$)$

o Sale $($S or s$)$

o Print $($P or p$)$

o Exit $($E or e$)$

$$ Do not assume the user will enter valid data.

o This means invalid entry for the menu, prices, stock quantity.

o Note $$ When selling, you cannot sell more stock than you have! Keep that in mind.

$$ If the user selects Buy, then prompt the user for the three$-$letter symbol, the quantity, and the price.

$$ If the user selects Sale, then prompt the user for the three$-$letter symbol, if the symbol exists in those bought,

then prompt for the quantity sold and price. Make sure you do not sell more than the number of stocks

available.

o Display the number of units sold at each purchase price and the total amount for the sale, the tax, and

the total take$-$home. Use the example above as a test case. Your output should be formatted to two

decimal places.

$$ If the user selects Print, then display the name of the stock along with all number of shares and the purchase

price. Remember, you may have multiple copies of the same share.

$$ If the user selects Exit, then close the application.

$$ You may use any number $/$ combinations of the data structures we have discussed in class.

$$ Use user$-$defined methods for user input, validation, calculations, etc...

$$ Do not forget the DocString Comment in your functions.

o Note $$ Your menu should be in its own module and called from main
