Prerequisites you need to know:

What is a Python Dictionary?

Python dictionary is the collection of key:value pairs. A pair in the dictionary is the combination of a key:value. It is mutable in nature, meaning once defined it can be changed. Data in the dictionary stored in ordered within curly braces {} and does not allow duplicate data.

What is a Python def function?

In Python, def is a reserved keyword used to create a customized function in Python.

What is a Python while loop?

Loop in Python defines – something going on or continuing in process. Python has two types of loop – for loop and while loop. Python while loop is used for a situation where the condition is True, meaning as long as the condition is True, we use while loop.

What is a Python conditional statement?

Python conditional statement refers to the if..elif..else clause which is used to define the conditions in Python. It is used in situations where execution depends upon the conditions.

Introduction: A Real world Challenge

In earlier days, we had never thought talking to an AI agent could give instant solutions to our daily routine problems like: what’s the weather today? What’s the currency conversion rate? But now in today’s AI world it is possible!

Ever wanted to build your own chatbot? Today, we’ll create a simple yet smart chatbot using Python — step by step! Let’s jump in!

Breaking Down the Problem

  1. Pass question as an Input

  2. Match Input with the predefined responses

  3. Give meaningful replies

Step 1: Define responses

Python Dictionary – key:value | key – input | value – output

				
					responses = {
        "hello":"Hey there! How can I help you today?",

        "tell me a joke": "Why do Python programmers prefer dark mode? Because light attracts bugs! 🐛😂",

        "what is today's weather?": "It is 34 degree celcius with Mostly Cloudy sky. ☁️",

        "how are you?": "I'm just a chatbot, but still feeling great! 😎",
        
        "bye": "Goodbye! Have a great day! 🚀",

        "default": "Hmm... I don't know how to respond to that. 🤔"
}
				
			

Explanation: A variable is defined as “responses” which is actually a dictionary and stored inputs and outputs in key:value pair. Inputs are the messages we type in the chatbot and outputs are the responses the chatbot will return.

Step 2: Chatbot function

				
					def chatbot():
    print("🤖 Chatbot: Hi! Type 'bye' to exit.")
    while True:
        user_input = input("You: ").strip().lower()
        if user_input == "bye":
            print("🤖 Chatbot: " + responses["bye"])
            break
        print("🤖 Chatbot:", responses.get(user_input, responses["default"]))

chatbot()
				
			

Explanation: while loop is used to represent the condition of asking the question – as long as the question is being asked, the condition is True. In other words, the loop handles the chat flow, until the user types ‘bye’ to exit.

If user wants to input the question:

Next, we used the input() function to take input or ask questions from the user to pass it to the chatbot, along with this used strip() method to remove whitespace and also used lower() method to convert the input or message to lowercase.

Now, by using the get() method, chatbot receives the user’s message from user_input and returns the output for that message, else if no input is present in the “responses”, then an output will be returned from the “default” input.

If user wants to quit the chat:

Next, we used the conditional statement “if”, to define the situation – if the user wants to quit the conversation with the chatbot. In this case, chatbot returns the output from the dictionary (responses) corresponding to the ‘bye’ input. Finally, to stop the conversation, use the “break” keyword.

Now it’s YOUR turn!

Now let’s create your own chatbot with some funny and surprising queries and let’s see what weird responses we get from our chatbots.
