#This Application is designed to analyze the stock JD.com and get the Holding-Period Return Value (HPR)

#Import the stock class I made for the program
from stock import Stock

#Def main function
def main(Y):

    #inputs for stock symbol and name
    A1 = input("Enter the ticker symbol of the stock: ")
    A2 = input("Enter the name of the stock: ")

    #Input the cash dividend
    A5 = float(input("Enter the dividend [If there isn't a dividend for that year, enter 0]: "))
