How to use ChatGPT in Python - Unofficial ChatGPT Python API Guide

To use ChatGPT in Python, you can make use of the OpenAI API to interact with the model. Here's an unofficial guide to get you started:

  1. Install the required libraries:
   pip install openai
Enter fullscreen mode Exit fullscreen mode
  1. Import the necessary modules:
   import openai
   import json
Enter fullscreen mode Exit fullscreen mode
  1. Set up your API key:
   openai.api_key = 'YOUR_API_KEY'
Enter fullscreen mode Exit fullscreen mode

Make sure to replace 'YOUR_API_KEY' with your actual OpenAI API key. If you don't have one, you can sign up for access on the OpenAI website.

  1. Make a function to send a message to ChatGPT:
   def send_message(message):
       response = openai.Completion.create(
           engine='text-davinci-003',
           prompt=message,
           max_tokens=100,
           temperature=0.7,
           top_p=1.0,
           n=1,
           stop=None,
           timeout=15
       )
       reply = response.choices[0].text.strip()
       return reply
Enter fullscreen mode Exit fullscreen mode

In this function, we use the openai.Completion.create method to send a prompt to the ChatGPT model and retrieve a response. You can adjust the parameters according to your needs.

  1. Use the send_message function to start a conversation:
   conversation = [
       {'role': 'system', 'content': 'You are a helpful assistant.'},
       {'role': 'user', 'content': 'Who won the world series in 2020?'}
   ]

   messages = [{'role': role, 'content': content} for role, content in conversation]
   prompt = json.dumps(messages)

   reply = send_message(prompt)
   print(reply)
Enter fullscreen mode Exit fullscreen mode

The conversation is represented as a list of messages, where each message has a role ('system', 'user', or 'assistant') and content (the text of the message). You can modify the conversation list to suit your own conversation.

The messages are then converted to a JSON format and passed to the send_message function, which returns the assistant's reply.

That's it! You now have a basic setup to interact with ChatGPT using Python. Remember to be mindful of OpenAI's API usage guidelines and respect any rate limits or restrictions in place.
