只执行一个 IF 直到值改变

Question

我正在尝试抓取一个网页来分析一些鞋子的库存，我按照我的意愿做了，但我需要添加一件事，例如，当突然有一个库存鞋码，它向我发送了一个有库存尺寸的 Discord webhook，但它一直向我发送 webhook 直到它停止有库存，问题是当它满足 if 的功能时我想这样做，它会发送webhook，但是下次我检查是否有库存时，请不要向我发送任何webhook，直到缺货然后再重新入库，我不知道我是否解释得很好。

我希望它只执行一次就完成该功能，即使它继续执行该功能，仅在库存状态返回到缺货然后再到有库存时再次执行它

这是我的代码：

from dhooks import Webhook, Embed
import requests

from json import loads

您可以创建一个在发送 webhook 时变为 True 的布尔值，然后查找该值是否为 false 以便发送电子邮件。代码是这样的：

if not "OUT_OF_STOCK" in disponibilidad3[numero] and not enviado:
    
    enviado = True    
    hook = Webhook('')
    embed = Embed(
    color=15105570,
    timestamp='now'  # sets the timestamp to current time
    )

    embed.url = (url)
    embed.title = (nombre+" " + color)
    embed.add_field(name='Talla', value="["+tallas3[numero]+"]("+api+skus5[numero]+")")
    embed.add_field(name='Precio', value=precio)
    embed.add_field(name='Useful Links', value="[Checkout](https://www.zalando.es/checkout/confirm)", inline=False)
    
    embed.set_footer(text='Zalando by SilverPings', icon_url="https://assets.stickpng.com/thumbs/5a32a860cb9a85480a628f95.png")

    embed.set_thumbnail(imagen)

    hook.send(embed=embed)
    print("[",datetime.datetime.now().hour,":",datetime.datetime.now().minute,":",datetime.datetime.now().second,"]", " Stock encontrado: ("+nombre + " - " + tallas3[numero]+")")

    numero = numero+1

else:
    numero = numero+1
    if numero == len(tallas3):
        break

如果你想发送另一个 webhook，你可以更新这个布尔值，但我会把它留给你。
