Python使用elif提供了一个很好的流控制结构，参见这里的官方文档：https://docs.python.org/3/tutorial/controlflow.html
所以这个想法是所有的语句都作为一个单元来计算。

if response==("tired"):
                Tired=['I wish I can make you feel better.','I hope school is not making you feel stressed.','You deserve the right to relax.']
                print(random.choice(Tired))

elif response==("yes"):
                yes=["Don't worry, you will be home soon......",'I am protecting your family and loved ones, trust me on this.',"Your kingdoms has been waiting for a long time, they'd forgiven your mistakes"]
                print(random.choice(yes))

elif response==("my mom"):
                print("Mom will be in town soon")
else:
    exit()

现在，语句将一直运行，直到其中一条语句为True。如果所有语句都为false，则默认为else语句。

代替

if
else: exit

if
else: exit

if
else: exit

执行以下操作：

if

elif:

elif:

else: exit

因为否则，如果第一个if为false，则将退出并且不检查其他的。

import random

name = input("What is your name? ")

def main():

    def feeling():
        response = input("How are you feeling right now {name}?".format(name=name))
        if response == "tired":
            tired = ['I wish I can make you feel better.','I hope school is not making you feel stressed.','You deserve the right to relax.']
            print(random.choice(tired))
        else:
            exit()

    def homesick():
        response = input("Do you miss your home? ")
        if response == "yes":
            yes=["Don't worry, you will be home soon......",'I am protecting your family and loved ones, trust me on this.',"Your kingdoms has been waiting for a long time, they'd forgiven your mistakes"]
            print(random.choice(yes))
        else:
            exit()

    def miss():
         response = input("Who do you miss?")
         if response == "my mom":
             print("Mom will be in town soon")
         else:
             exit()

    prompts = [feeling, homesick, miss]
    random.choice(prompts)()

    main()

您应该将提示和聊天机器人的预期答案和回复分组，例如，以(prompt, expected_answer, [some, possible, replies])的形式作为元组

feeling = ("How are you feeling right now " +str(x)+"? ", "tired",
           ['I wish I can make you feel better.','I hope school is not making you feel stressed.','You deserve the right to relax.'])
miss = ...
homesick = ...

prompts = [feeling,homesick,miss]
choice = random.choice(prompts)()

prompt, ans, replies
resp = input(promp)
if resp == ans:
    print(random.choice(replies))
else:
    exit()

这也将使它更容易扩展您的聊天机器人与更多的问题/答案对，也提供不同的聊天机器人答复不同的用户答案。

不理解您的代码，但您可以执行以下操作：

if response!=("tired"):
    exit()
    return

Tired=['I wish I can make you feel better.','I hope school is not making you feel stressed.','You deserve the right to relax.']
print(random.choice(Tired))

if response!=("yes"):
    exit()
    return

yes=["Don't worry, you will be home soon......",'I am protecting your family and loved ones, trust me on this.',"Your kingdoms has been waiting for a long time, they'd forgiven your mistakes"]
print(random.choice(yes))
