通过BeautifulSoup提取随机数据

-1

我目前正在构建一个Python IRC bot。我发现了一些从bash.org提取数据并向该频道发布随机引用的内容。我试着修改它来从另一个源拉取 - 修改它正在查看的类 - 但它最终以“调用Python对象时超出最大递归深度”错误而出错。此时我正在拉我的头发。任何的意见都将会有帮助。通过BeautifulSoup提取随机数据

实际的错误可能会有所帮助 – 2015-02-06 19:00:45

Python有一个有限的递归深度，所以问题，可能打这个限制，你最好拿出一个迭代版本的算法。如果你懒得这样做，并且确定你的递归总是总是只比Python设置的默认限制更深一点，你可以通过改变这个限制逃脱。怎么会这样？头向What is the maximum recursion depth in Python, and how to increase it?
