如何多次调用此函数？

Question

#calculates total price of your items as your shopping

print("The sales tax in Lucas County is 7.25%")
sales_tax = 0.0725
price_total=0

price = float(input("Insert price of item "))
price_tax= price * sales_tax
price_semitotal = price_tax + price
print("Price of that item with tax: ", price_semitotal)
price_total+=price_semitotal
print("Total Price: ", price_total)

如何更改它以使其循环并不断提示用户添加更多项目？ 我希望它像一个购物清单，您可以在其中输入一件商品的价格，它会计算税款，以便您可以看到该商品的最终价格以及所有商品的最终价格。 我也尝试过这样的事情，但没有奏效：

print("The sales tax in Lucas County is 7.25%")
sales_tax = 0.0725
price_total=0
def price(price_input, price_tax, price_semitotal, price_total): 
    price_input = float(input("Insert price of item "))
    return price_tax = price_input * sales_tax
    return price_semitotal = price_tax + price
    print("Price of that item with tax: ", price_semitotal)
    return price_total+=price_semitotal
    print("Total Price: ", price_total)

while True:
    price

Answer 1

print("The sales tax in Lucas County is 7.25%")
price_total=0
sales_tax = 1.0725
def price():
    price_input = float(input("Insert price of item "))

    price_tax = price_input * sales_tax
    return price_tax

while True:
    x = price()
    print(f"Price of that item with tax: {x:.2f}")
    price_total += x
    print(f"Total Price: {price_total:.2f}")
    if x == 0:
        break

sales_tax = 1.0725 está substituindo

return price_tax = price_input * sales_tax
return price_semitotal = price_tax + price

{x:.2f} usei para usar apenas duas casas decimais。

Sua base na linguagem não está boa, procure video e livros para melhorar。

Quando price_input 用于igual a 0 o 循环阿卡巴。

Answer 2

这是正确的代码，但这真的不是你应该问这种事情的地方，Stack Overflow 是针对文档等中未回答的问题。你真的可以从文档和教程中获取什么

print("The sales tax in Lucas County is 7.25%")
def price(): 
    sales_tax = 0.0725
    price_total=0
    price_input = float(input("Insert price of item "))
    price_tax = price_input * sales_tax
    price_semitotal = price_tax + price_input
    print("Price of that item with tax: ", price_semitotal)
    price_total+=price_semitotal
    print("Total Price: ", price_total)

while True:
    price()
