How to Use ChatGPT from Python: A Quick Guide


Chatbots have become an integral part of many applications and services, offering real-time interaction with users. If you’re looking to integrate OpenAI’s ChatGPT into your Python project, you’re in the right place. In this short guide, we’ll walk you through the process of setting up and using ChatGPT in Python.


Before you get started, make sure you have the following prerequisites in place:

  1. OpenAI API Key: You need an OpenAI API key to access their services. You can sign up for one on the OpenAI platform.
  2. Python Installed: Ensure you have Python installed on your machine. You can download it from the official Python website (
  3. OpenAI Python SDK: Install the OpenAI Python SDK using pip by running the following command:
   pip install openai

Setting Up Your OpenAI API Key

Replace "yourapikeyforopenai" in your Python code with your actual OpenAI API key. You can find your API key in your OpenAI dashboard.

openai.api_key = "yourapikeyforopenai"

Creating the Chatbot Function

In your Python script, you can define a function to interact with ChatGPT. Here’s your chatbot_response function:

import openai

def chatbot_response(prompt):
    completions = openai.Completion.create(

    message = completions.choices[0].text
    return message.strip()

This function sends a prompt to the ChatGPT model and retrieves its response. You can customize the parameters such as engine, max_tokens, and temperature to control the behavior of the model based on your specific requirements.

Interacting with the Chatbot

Now that you have set up the chatbot_response function, you can interact with your ChatGPT-based chatbot in a loop. Here’s how you can do it:

while True:
    user_input = input("You: ")
    response = chatbot_response(user_input)
    print("Chatbot:", response)

This code continuously prompts you for user input, sends it to the ChatGPT model, and displays the model’s response. You can run this script to have a conversation with your chatbot powered by ChatGPT.


Integrating ChatGPT into your Python application is a straightforward process. By following these steps, you can create a chatbot that can provide responses based on user input. Remember to adhere to ethical guidelines when using AI models like ChatGPT, and keep experimenting to fine-tune your chatbot’s performance for your specific use case.
