python-3.x - 检查多个字符串是否在另一个字符串中

Question

我正在制作一个聊天机器人，它会查找特定术语以做出相关响应，但我正在努力寻找一种从字符串中查找关键词的方法。

我已经尝试过使用word.find()，word in str但我可能在其中的某个地方提出了问题。

while True:
    user = input("what's up?")
    if "sad" or "unhappy" or "depressed" in user:
        print("oh that's quite sad")
    else:
        print("that's good")

无论我输入什么，它都会不断返回“哦，这很可悲”。

Answer 1

解决方案1：

while True:
    user = input("what's up?")
    if "sad" in user or "unhappy" in user or "depressed" in user:
        print("oh that's quite sad")
    else:
        print("that's good")

解决方案2：使用any

预先定义字符串并使用它：

mylist = ["sad","unhappy","depressed"]

while True:
    user = input("what's up?")
    if any([x in user for x in mylist]):
        print("oh that's quite sad")
    else:
        print("that's good")
