Python chatbot“TypeError:'NoneType'类型的参数不可读取”

Question

我正在创建一个聊天机器人，当用户问它一个特定的问题时，它应该简单地回应用户，机器人会检测到它的代码，并以正确的输出作出回应。但我需要帮助解决打字错误。在

我的代码：

user_name = input('''What would you like to be called: 
''')
bot_name = input('''
Now lets give you virtual bot a name: 
''')
print(' ')
print(f"{'Thank you'} {user_name} {'You have just summoned a new bot named'} {bot_name}!")

print('''

You may now have the permission to talk to the bot! HV

''')

import time
time.sleep(2)

import random
l = (bot_name + ":Hello!", bot_name + ":Hi!", bot_name + ":Hello!")
random_greeting = random.choice(l)
print(random_greeting)

def openinput(input):
    return print(input(f"{user_name}{':'}"))

if "how are you doing today" in openinput(input):
    print({bot_name} + 'Very Well! Thank you for asking :)')
elif "hi" in openinput(input):
    print('Hi!!')
else:
    print("ERROR1.0: It seem's like my index doesn't answer your question.")

错误：

Answer 1

错误来自这样一个事实：您试图在返回print语句的函数中迭代（使用in）。我把它换成了基于输入的变量属性，现在它起作用了：

user_name = input('''What would you like to be called: 
''')
bot_name = input('''
Now lets give you virtual bot a name: 
''')
print(' ')
print(f"{'Thank you'} {user_name} {'You have just summoned a new bot named'} {bot_name}!")

print('''

You may now have the permission to talk to the bot! HV

''')

import time
time.sleep(2)

import random
l = (bot_name + ":Hello!", bot_name + ":Hi!", bot_name + ":Hello!")
random_greeting = random.choice(l)
print(random_greeting)

user_input = input(f"{user_name}{':'}")

if "how are you doing today" in user_input:
    print({bot_name} + 'Very Well! Thank you for asking :)')
elif "hi" in user_input:
    print('Hi!!')
else:
    print("ERROR1.0: It seem's like my index doesn't answer your question.")

因为这是一个聊天机器人，我很确定你也会希望在重写用户输入时循环，这样你就可以计算新的语句了。像这样：

^{pr2}$
