I am trying to make an AI program in python with random module-CodePudding

I have been learning to make AI in python. I used the random module and the append command to give unknown input values. this is my code:

import random
greetings=["Hi there!","Sup!"]
goodbye=["have a nice day","byee!"]
keywords=["maths","swimming"]
responses=["one of the most interesting subjects","The best sport in the world"]
print(random.choice(greetings))
user=input("Chat with me(type 'bye' to quit) -> ")
user=user.lower()
keyword_found=False
while(user!="bye"):
    
    for i in range(len(keywords)):
        if(keywords[i] in user):
            print("Bot: " responses[i])
            keyword_found==True
    if(keyword_found==False):
        new_keyword=input("Couldn't get ya. pls tell me the name of the topic which you are talking about : ")
        keywords.append(new_keyword)
        new_response=input("Pls tell me about it : ")
        responses.append(new_response)
    user=input("Chat with me(type 'bye' to quit) -> ")
    user=user.lower()

The program is working fine with known inputs. But when i am using the append, the "Couldn't get ya" is popping up even after appending the new input. See the attached picture to understand the scenario.

Please help me to fix it. I would be really greatful

This is the output window

CodePudding user response：

Error in code at line 15 keyword_found==True, where you are not assigning variable but rather checking if True

Working code with minimum modifications:

import random
greetings=["Hi there!","Sup!"]
goodbye=["have a nice day","byee!"]
keywords=["maths","swimming"]
responses=["one of the most interesting subjects","The best sport in the world"]
print(random.choice(greetings))

user=input("Chat with me(type 'bye' to quit) -> ")
user=user.lower()
keyword_found=False

while(user!="bye"):
    for i, keyword in enumerate(keywords):
        if keyword in user:
            print("Bot: " responses[i])
            keyword_found=True
            break
            
    if not keyword_found:
        new_keyword=input("Couldn't get ya. pls tell me the name of the topic which you are talking about : ")
        keywords.append(new_keyword)
        new_response=input("Pls tell me about it : ")
        responses.append(new_response)
        
    user=input("Chat with me(type 'bye' to quit) -> ")
    user=user.lower()

CodePudding user response：

for i in range(len(keywords)):
    if(keywords[i] in user):
        print("Bot: " responses[i])
        keyword_found==True

The line

keyword_found==True

is for the equality operator, while you want to use the assignment operator:

keyword_found=True

Made 3 changes and it should work fine:

for i in range(len(keywords)):
    if (keywords[i] in user):
        print("Bot: "   responses[i])
        keyword_found = True # 1
        break # 2
if (keyword_found == False):
    new_keyword = input("Couldn't get ya. pls tell me the name of the topic which you are talking about : ")
    keywords.append(new_keyword)
    new_response = input("Pls tell me about it : ")
    responses.append(new_response)
keyword_found = False # 3
user = input("Chat with me(type 'bye' to quit) -> ")
user = user.lower()
