python - while True 循环脚本停止运行，没有终止或抛出错误

Question

从循环运行此代码，它不会终止或似乎结束？没有捕获/抛出错误。一旦它位于输出控制台的第 189 行，它总是会执行此操作。

import time
from requests_html import HTMLSession

product_urls = ["https://footdistrict.com/en/adidas-yeezy-boost-700-ee9614.html", "https://footdistrict.com/en/adidas-yeezy-boost-350-v2-static-ef2905.html"]
session = HTMLSession()

def monitor():
    try:
        for url in product_urls:
            print("Searching for url: {} ...\n".format(url))
            r = session.get(url,timeout=20)
            r.html.render()
            search = r.html.find(("#attribute134"), first =True)

            if search is not None: 
                print("Item is in stock.")  
            else:
                print("Item is out of stock.")
    except Exception as e:
        print(e)

    time.sleep(3)

while True:
    monitor()

是不是某种内存错误导致了这种情况？我试图增加到time.sleep(3)类似的东西，time.sleep(30)但这没有任何区别，在控制台的第 189 行之后仍然停止运行？
