ThreadでAPI処理待ちのアスキーアニメーションをだす

OpenAPIの処理が延々とかかって心理的にアレなので

実際のところ

from openai import OpenAI
from dotenv import dotenv_values
import threading
import time
import sys

def loading_animation(event):
    animation_chars = ['|', '/', '-', '\\']
    i = 0

    while not event.is_set():
        sys.stdout.write('\r' + animation_chars[i % len(animation_chars)])
        sys.stdout.flush()
        time.sleep(0.1)
        i += 1

    # Clean Up
    sys.stdout.write('\r\rDone!         \n')

def genImage(client,response_event):
  response = client.images.generate(
    model="dall-e-3",
    prompt="a black cat on an american classic car.",
    size="1024x1024",
    quality="standard",
    n=1
  )

  response_event.set()
  return response


print("process start")

config = dotenv_values(".env")

yourclient = OpenAI( api_key= config["OPENAI_API_KEY"] )

response_event = threading.Event()

animation_thread = threading.Thread(target=loading_animation, args=(response_event,))
animation_thread.start()


result = genImage(yourclient,response_event)
image_url = result.data[0].url
print(image_url)

animation_thread.join()
