urllib.error.HTTPError: HTTP Error 429: Too Many Requests

urllib.error.HTTPError: HTTP Error 429: Too Many Requests是指客户端发送请求过于频繁，导致服务器无法处理。HTTP 429状态码表示太多请求，也就是服务器拒绝为了保护自己的资源而满足客户端请求。这通常是因为客户端在短时间内发送了过多的请求，或者服务器设置了某种限制（如API限制）。

如果你遇到了这个错误，可以尝试减少请求的频率或者等待一段时间后再发送请求。此外，你也可以联系服务器管理员，了解是否有其他方式可以更好地使用其服务。

python爬虫报错urllib.error.HTTPError: HTTP Error 420:

HTTP Error 420 means that the request has been refused due to too many requests or the rate limit has been exceeded. This error is commonly seen when web scraping or crawling websites without proper throttling or delay between requests.

To fix this error, you can try the following:

1. Add a delay between requests: You can add a delay of a few seconds between requests to avoid making too many requests in a short period of time.

2. Use a proxy: You can use a proxy server to make your requests appear as if they are coming from a different IP address, which can help you bypass rate limits.

3. Contact the website owner: If you are getting this error repeatedly, you can try contacting the website owner to see if they can increase the rate limit for your account.

4. Reduce the number of requests: If none of the above solutions work, you can try reducing the number of requests you make to the website. This may mean limiting the number of pages you scrape or only scraping the website at certain times of day.
