我每天都运行这个代码几周没有错误。今天早上，它适当地运行了for循环超过100次，然后给出了连接问题。每次我试图运行它，它将运行5到130次，但总是在完成之前给出连接错误。
我仍然获得200的状态代码。我在Python中看到一些引用“内存泄漏”问题的帖子，但我不知道如何弄清楚这是否是问题。这也很奇怪，因为它一直运作良好，直到今天。
我在同一站点上的其他页面的代码类似，但仍然可以正常运行。
这是代码：
import requests
from bs4 import BeautifulSoup
updates = []
print(f'Getting {total_timebanks} timebank details... ')
for timebank in range(len(timebanks)):
url = f"http://community.timebanks.org/{timebanks['slug'][timebank]}"
res = requests.get(url, headers=headers)
soup = BeautifulSoup(res.content, 'lxml')
update = {}
update['members'] = soup.find('div', {'class': 'views-field-field-num-users-value'}).span.text.strip().replace(',', '')
updates.append(update)
time.sleep(1)
这是完整的错误消息：

问题似乎已经解决了。如果没有对代码进行任何更改，它将在今天早上恢复运行。
我对昨天为什么会出现连接错误没有太多的了解，但它似乎确实是网站的问题，而不是代码。
谢谢你的回复！作为参考，我也尝试将睡眠定时器增加到30，但这并没有解决昨天的问题。
