Making a easy chatbot in Python

On this part, we are going to create a easy chatbot in Python. There are other ways to make a chatbot, from easy to advanced. Right here, we are going to solely use the perform and conditional statements to implement the chatbot’s program.

Let’s dive deep into chatbot coding!

#Let’s Create a Easy Chatbot in Python
#outline a greet perform
def greet(bot_name, birth_year):
#print the query solutions
    print(f”Chatbot: Hi there, I’m {bot_name}. I used to be created in {birth_year}.”)
    print(“Chatbot: How can I enable you to as we speak?”)

#Use one other Perform reply
def reply(user_input):
#use conditional statements
    if user_input.decrease() == “hello” or user_input.decrease() == “hiya”:
        return “Hi there there! How can I enable you to as we speak?”
    elif user_input.decrease() == “bye”:
        return “Goodbye! Have a terrific day.”
    elif user_input.decrease() == “what’s your good identify?”:
        return “My identify is Chatbot.”
    elif user_input.decrease() == “what’s your beginning yr?”:
        return “I used to be created in 2021.”
    elif user_input.decrease() == “what are you able to do?”:
        return “I can reply your questions, have a dialog with you, and carry out fundamental duties.”
    elif “climate” in user_input.decrease():
        return “I’m not capable of test the climate in the intervening time, sorry.”
        return “I’m sorry, I don’t perceive what you’re attempting to say. Might you please rephrase that?”

bot_name = “Chatbot”
birth_year = 2021
greet(bot_name, birth_year)

whereas True:
    user_input = enter(“You: “)
    response = reply(user_input)
    print(f”Chatbot: {response}”)
    if user_input.decrease() == “bye”:







This chatbot accommodates a greet perform that prints a greeting to the consumer when the chatbot begins. The response perform takes within the consumer’s enter and returns a response primarily based on the consumer’s command. The chatbot can reply questions on its beginning yr and identify, and it might carry out easy duties e.g. saying hiya and goodbye. If the consumer inputs one thing that the chatbot doesn’t perceive, it should reply to the consumer to rephrase their command.

This system reveals methods to create a fundamental chatbot in Python utilizing solely features and conditional statements. It additionally shows methods to perform a easy dialog with the consumer utilizing enter and output statements.
