Question

我在下面编写了程序。

不知何故，即使我只希望执行if distance == "..."，程序也会执行if pickup_location = "no"：命令。我的程序中可能遗漏了一些基本的东西，这些东西使我来到这里，因为我无法修复它并希望寻求您的帮助。提示我很好，所以我可以找出答案。

           "for the final price of", final_price, "Dollars, should you still want to buy it.")

else:
    print("What?")

这是适用于python 3的工作程序

注意：由于#This program calculates the final price, based on the base price of a car's production price #21.07 Author: 382df7181fcd71a41cfe9b793032c029d139ecb557a4af40ca5de3a148bbbc0d (SHA256) #parameters to be set sales_margin_percentage = 0.2 tax_rate = 0.23 license_rate = 0.12 dealers_cut = 0.05 delivery_fee_10_100 = 400 delivery_fee_100_250 = 1050 production_price = int(input("How much did it cost to produce the car?")) #calculations of extra fees sales_margin = production_price * sales_margin_percentage internal_sales_price = production_price+sales_margin tax = internal_sales_price * tax_rate license_fee = internal_sales_price * license_rate pre_external_sales_price = internal_sales_price + tax + license_fee dealer_prep = pre_external_sales_price * dealers_cut final_price = pre_external_sales_price + dealer_prep pickup_location = str(input("Do you want to collect the car at the dealer ship?")) if pickup_location == "yes": print("Ok.

That will mean that you can profit of our free home delivery service and can receive " "your car for the final price of", final_price, "dollars.") elif 10 < distance <= 100: print("Awesome. You can buy and get your car delivered to the front door for the final price of", final_price + delivery_fee_10_100, "Dollars.") elif 100 < distance <= 200: print("Awesome. That means that you can buy and get the car delivered for the final price of", final_price + delivery_fee_100_250, " to your front lawn.") else: print("I'm sorry. A home delivery is not possible for your location, however, you can pick it up at the dealer ship " "for the final price of", final_price, "Dollars, should you still want to buy it.") else: print("What?")是多余的，因此我确定了最终距离，我认为您的意思是distance > 100 and distance > 200。您可能需要在最终的if else语句上修改参数。它们与打印的声明不符（例如<= 200）。

程序无法将语句识别为if-elif语句的子命令。为什么？
