Question

def load():    
    name=0
    count=0
    totalpr=0
    name=input("Enter stock name OR -999 to Quit: ")
    while name != '-999':
        count=count+1
        shares=int(input("Enter number of shares: "))
        pp=float(input("Enter purchase price: "))
        sp=float(input("Enter selling price: "))
        commission=float(input("Enter commission: "))
        name=input("Enter stock name OR -999 to Quit: ")

def calc():
    totalpr=0
    amount_paid=shares*pp
    commission_paid_purchase=amount_paid*commission
    amount_sold=shares*sp
    commission_paid_sale=amount_sold*commission
    profit_loss=(amount_sold - commission_paid_sale) -(amount_paid + commission_paid_purchase)
    totalpr=totalpr+profit_loss

def display():
    print("\nStock Name:", name)
    print("Amount paid for the stock:       $",      format(amount_paid, '10,.2f'))
    print("Commission paid on the purchase: $", format(commission_paid_purchase, '10,.2f'))
    print("Amount the stock sold for:       $", format(amount_sold, '10,.2f'))
    print("Commission paid on the sale:     $", format(commission_paid_sale, '10,.2f'))
    print("Profit (or loss if negative):    $", format(profit_loss, '10,.2f'))
    print("Total Profit is $", format(totalpr, '10,.2f'))

def main():
    load()
    calc()
    display()

main()

输入佣金后，程序应立即运行计算并相应显示信息。但是现在，它只是循环而不显示/计算任何东西。

我想维护程序本身的结构 -

def main():
load()
calc()
display()

但是还有一些阻碍程序将结果载入calc然后按顺序显示的东西。

我的经验不足（这是为了上课）？加载股票信息后，它可能会在while循环中踢出。没有（在我看来）任何告诉程序进入calc（）然后移动到display（）的东西......我认为它是用def main（）：序列实现的，但我可能是错的。

这就是输出的样子：
