Question

我在我的代码行中创建了嵌套条件，但是如果任何其他“（书籍）条件”条件不“好”，我想跳过它们。

condition = input("What is the condition of the book? ")
age = input("Is the book old or new? ")
cover = input("What type of cover does it have? ")


if condition == "good":
    if age == "new":
        if cover == "hardcover":
            print("We can offer you a high price")
        elif cover == "papercover":
            print("We can offer you a medium price")
    elif age == "old":
        print("We can offer you a medium price")
elif condition == "poor":
    print("We can offer a low price")
elif condition == "terrible":
    print("Sorry we cannot accept this book")
else:
    print("I do not understand, please leave the store")

您需要将输入移动到if语句中，这样就可以使用已经存在的if-else结构，如下所示：

condition = input("What is the condition of the book? ")

if condition == "good":
    age = input("Is the book old or new? ")
    if age == "new":
        cover = input("What type of cover does it have? ")
        if cover == "hardcover":
            print("We can offer you a high price")
        elif cover == "papercover":
            print("We can offer you a medium price")
    elif age == "old":
        print("We can offer you a medium price")
elif condition == "poor":
    print("We can offer a low price")
elif condition == "terrible":
    print("Sorry we cannot accept this book")
else:
    print("I do not understand, please leave the store")

如果Python中的语句跳过
