Error while using openai in Jupyter notebook for prompts repsonse. Please help

[mohitkothari0iit0isb]

I am trying to get openai in Jupyter notebook at local host. I used code mentioned in description but I am getting error as described below. Please tell me what can be done to run the code. Please help in solving this basic error (I am using paid version of chatgpt)

Code used in Jupyter notebook
`
!pip install openai certifi
!pip install certifi
!pip install openai
!pip install openai certifi requests pandas

import os
import openai
import certifi
import requests
import pandas as pd

Set your OpenAI API key as an environment variable

os.environ['OPENAI_API_KEY'] = Had put my key here

Retrieve the API key from environment variables

openai.api_key = os.getenv('OPENAI_API_KEY')

Create a custom requests session

session = requests.Session()
session.verify = certifi.where()

def query_openai(prompt):
headers = {
'Content-Type': 'application/json',
'Authorization': f'Bearer {openai.api_key}',
}
json_data = {
'model': 'gpt-3.5-turbo',
'messages': [
{'role': 'system', 'content': 'You are a helpful assistant.'},
{'role': 'user', 'content': prompt}
],
}
response = session.post('https://api.openai.com/v1/chat/completions', headers=headers, json=json_data)
response.raise_for_status() # Raise an error for bad status codes
return response.json()

Test the function

prompt = "Explain the relationship between price and sales in a dataset."
response = query_openai(prompt)
print(response['choices'][0]['message']['content'].strip())
`

While running this code I am getting this error:
SSLError: HTTPSConnectionPool(host='api.openai.com', port=443): Max retries exceeded with url: /v1/chat/completions (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1002)')))
