Question

In python:

Write a class to create a stock class. That stock class should initialize the following information: symbol, shares, initial price, and current_price. An object should be printed as follows:

Stock Symbol: ….

Shares: …

Initial Price:...

Current Price: ….

There should be methods to buy stock (adds to the shares count) and sell stock (deducts shares). You should ensure that you cannot have negative shares. When you sell a stock you will need to update the current price to what it is sold at in addition you will need to print the amount gained or lost.

# Code

class stock:

    # constuctor to initialize symbol, shares, initial_price, and current_price

    def __init__(self, symbol, shares, initial_price, current_price):

        self.symbol = symbol

        self.shares = shares

        self.initial_price = initial_price

        self.current_price = current_price

    # print

    def __str__(self):

        return f'\nStock Symbol: {self.symbol}\nShares: {self.shares}\nInitial Price: {self.initial_price}\nCurrent Price: {self.current_price}'

    # buy stock

    def buy(self, count):

        self.shares += count

    # sell stock

    def sell(self, count, price):

        if self.shares-count > 0:

            self.shares -= count

            # update current price

            self.current_price -= price

            # check for gain or loss

            if self.current_price/self.shares > self.initial_price/self.shares:

                print(

                    f'Amount gained: {self.current_price/self.shares-self.initial_price/self.shares}')

            else:

                print(

                    f'Amount gained: {self.initial_price/self.shares-self.current_price/self.shares}')

        else:

            print("\nNot enough shares")

# testing above class

testing = stock("GK", 10, 200, 200)

# print stock

print(testing)
