```

gpt-3.5.py

#!/usr/bin/env python3

import os
import openai
from dotenv import load_dotenv

# Load environment variables from .env file
load_dotenv()

# Set OpenAI API key from environment variable
openai.api_key = os.getenv("OPENAI_API_KEY")

# Set GPT-3.5 model ID
model_id = 'gpt-3.5-turbo'

# Define function to send a message to the OpenAI API and get a response
def chat_gpt_conversation(conversation):
    # Send the conversation to the OpenAI API and get a response
    response = openai.ChatCompletion.create(
        model=model_id,
        messages=conversation
    )

    # Add the assistant's message to the conversation
    conversation.append({
        'role': response.choices[0].message.role,
        'content': response.choices[0].message.content
    })

    # Return the updated conversation
    return conversation

# Define function to display a message from the conversation
def display_message(message):
    print(f"{message['role'].capitalize()}: {message['content'].strip()}\n")

# Initialize an empty conversation
conversation=[]

# Start the conversation loop
while True:
    # Get user input
    user_input = input('User: ')

    # Add the user's message to the conversation
    conversation.append({'role': 'user', 'content': user_input})

    # Send the conversation to the OpenAI API and get a response

User: I want to bake a cake but don't know what temperature to set the oven to.
Assistant: The oven temperature for baking a cake will depend on the type of cake and the size of the tin you are using. Here are some general guidelines to help you set the right temperature for your cake:

1. For sponge cakes, which contain a lot of eggs and sugar, preheat your oven to 350°F (180°C). This temperature works well for most sponge cakes, regardless of their size.

2. For chocolate cakes, which contain cocoa powder and sometimes melted chocolate, set your oven to 325°F (160°C) to ensure that the chocolate does not burn.
