numCat = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
print("Hello user, I am Inverted Cheese.\n")
username = input("What is your name?\n").capitalize()
print("Hello, " + username + "!")

while True:
    if input() == "hello":
        print("Hello, " + username + "!")

        num = randrange(0,10)
        print(num)
        if num == 0:
            numcat[num] += 1
            print("You now have " + numcat[num] + "brown cats")
        elif num == 1:
            numcat[num] += 1
            print("You now have " + numcat[num] + "grey cats")

    elif input() == "inventory1":
        print("hi)")
        print("Inventory Part I:\n\nCommon Cats:\nBrown: " + numCat[0] + "\nGrey " + numCat[1] + "\nWhite: " + numCat[2] + "\nBlack: " + numcat[3] + "\nOrange: " + numCat[4] + "\n\nRare Cats:\nFurless: " + numCat[5])

        print("hi)")

input()

唯一有效的命令是“ hello”命令，但“ cat”和两个清单命令都不起作用。当我尝试使用它们时，没有任何输出。有人可以解释为什么吗？

它也不会打印任何内容。我已经在清单代码中添加了打印命令，但是它们不会打印。我的清单有问题吗？

我真的很想让这个程序运行，但是我在这里完全迷路了。

Answer 1

您将在每个@Retention(AnnotationRetention.SOURCE) @Target(AnnotationTarget.FIELD) annotation class ReflectSource(val value: Int) @Retention(AnnotationRetention.BINARY) @Target(AnnotationTarget.FIELD) annotation class ReflectBinary(val value: Int) @Retention(AnnotationRetention.RUNTIME) @Target(AnnotationTarget.FIELD) annotation class ReflectRuntime(val value: Int)评估中读取新输入。将输入存储一次，以便您可以反复进行比较：

elif

Answer 2

每次调用input()时，都需要用户再次输入。您应该调用一次input()并将返回值存储在变量中以进行比较：

while True:
    command = input()
    if command == "hello":
        print("Hello, " + username + "!")
    elif command == "cat":
        num = randrange(0,10)
        print(num)
        ...

有人可以告诉我为什么我的代码不起作用吗？
