Question

我正在尝试编写某种多选类游戏，但是无论输入如何，即使输入是d或D，总是会触发if语句。

这可能是一个明显的错误，但是我是编程的绝对初学者，所以我真的希望你们能帮助我指出我做错了什么。

我的代码如下：

answer = input("Do you want to do something (C) or something else (D)? [C/D]")

if answer == "c" or "C":
    print ("You typed", answer)
    time.sleep(2)
    print ("You can now do something")
    time.sleep(2)


elif answer == "d" or "D":
    print ("You typed", answer)
    time.sleep(2)
    print ("You can now do something else")
    time.sleep(2)


else:
    Exit()

Answer 1

answer = input("Do you want to do something (C) or something else (D)? [C/D]")

if answer == "c" or answer == "C": # Here is your mistake
    print ("You typed", answer)
    time.sleep(2)
    print ("You can now do something")
    time.sleep(2)


elif answer == "d" or answer == "D":  # also here
    print ("You typed", answer)
    time.sleep(2)
    print ("You can now do something else")
    time.sleep(2)


else:
    Exit()

Answer 2

Python的工作方式不同于英语。

if answer == "c" or "C":应该是if answer == "c" or answer == "C": 对于D同样。
