如何使Python bot回复列表中的相同数字

Question

例如，我做了这样的代码： etch = [“你好”，“嗨”] 关键字= [“ hi”，“ Hello”] 我该如何制作，以便发送相同的列表号码？例如，Hello在问候列表上是0，所以我会发送HI，因为关键字列表上的0是0？

Answer 1

这就是您的想法：

greetings = ["hi", "hello", "yo"]
keywords = ["Hi!", "Hello!", "Yo!"]

while True:

    user = input("what would you like to say?: ")

    if user == "bye":
        break

    try:
        print(keywords[greetings.index(user)])
    except ValueError:
        print('I don\'t know how to reply.')

更多的Pythonic是：

answers = {"hi": "Hi!",
           "hello": "Hello!",
           "yo": "Yo!"}

while True:
    
    user = input("what would you like to say?: ")
    
    if user == "bye":
        break
    
    try:
        print(answers[user])
    except KeyError:
        print('I don\'t know how to reply')

或：

from collections import defaultdict

answers = defaultdict(lambda:'I don\'t know how to reply.')
answers.update({"hi": "Hi!",
                "hello": "Hello!",
                "yo": "Yo!"})

while True:
    user = input("what would you like to say?: ")
    if user == "bye":
        break
    print(answers[user])
