将上面程序合并为一个程序文件

以下是将两个程序合并为一个程序文件的代码：

import openai
import requests
import json

# OpenAI API credentials
openai.api_key = "YOUR_API_KEY"

# CSDN API credentials
csdn_app_key = "YOUR_APP_KEY"
csdn_app_secret = "YOUR_APP_SECRET"
csdn_username = "YOUR_USERNAME"
csdn_password = "YOUR_PASSWORD"

# Authenticate CSDN API
response = requests.post(
    url="https://passport.csdn.net/v1/api/authorize",
    params={
        "client_id": csdn_app_key,
        "response_type": "code",
        "state": "random_string",
        "redirect_uri": "http://localhost",
        "display": "default"
    },
    headers={
        "Content-Type": "application/json",
        "User-Agent": "Mozilla/5.0"
    },
    auth=(csdn_username, csdn_password)
)
auth_code = json.loads(response.text)['data']['auth_code']

# Use auth code to get access token
response = requests.post(
    url="https://gitee.com/oauth/token",
    params={
        "grant_type": "authorization_code",
        "code": auth_code,
        "client_id": csdn_app_key,
        "redirect_uri": "http://localhost",
        "client_secret": csdn_app_secret
    },
    headers={
        "Content-Type": "application/json",
        "User-Agent": "Mozilla/5.0"
    }
)
access_token = json.loads(response.text)['access_token']

# Chat with OpenAI GPT-3
def chat_with_openai(prompt):
    response = openai.Completion.create(
        engine="davinci",
        prompt=prompt,
        max_tokens=150,
        n=1,
        stop=None,
        temperature=0.5
    )

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

# Chat with CSDN ChitGPT
def chat_with_csdn(prompt):
    response = requests.post(
        url="https://aiapi.csdn.net/sdk/chit_chat",
        headers={
            "Content-Type": "application/json",
            "User-Agent": "Mozilla/5.0",
            "Authorization": f"Bearer {access_token}"
        },
        json={
            "msg": prompt
        }
    )

    message = json.loads(response.text)['data']['reply']
    return message.strip()

# Main loop
while True:
    user_input = input("You: ")
    if user_input.lower() == "bye":
        print("Bot: Bye!")
        break

    openai_response = chat_with_openai(user_input)
    print("OpenAI: " + openai_response)

    csdn_response = chat_with_csdn(user_input)
    print("CSDN: " + csdn_response)

请注意，您需要将 `YOUR_API_KEY`，`YOUR_APP_KEY`，`YOUR_APP_SECRET`，`YOUR_USERNAME` 和 `YOUR_PASSWORD` 替换为您自己的 API 密钥和凭据。
