没有递归的Python递归错误？

Question

I'm new to python, and I'm building a web crawler for funsies/educational purposes. I don't use any recursive functions, but I still get the 'RuntimeError: maximum recursion depth exceeded' error. I'm really confused, and kinda feel like I'm missing something obvious or just misunderstanding something. Am I somehow recursing, or could it be related to my large loops? The idea is to crawl the web until you've crawled 10k pages.

Looks like my issue is trying to call str() on a URL that is not encoded properly. I've tried decoding the URLs and then ecoding them to unicode, but I was never able to do it successfully. Any advice would be greatly appreciated!

Answer 1

The code you gave us doesn't actually run (it's missing all the import statements, and it has indentation errors, and so on), and it requires a JET database we don't have and a third-party module to read it, and it's hardcoded to use pre-existing directories in your home directory.

I've attempted to fix all of that at http://pastebin.com/rCJriEu5 (which requires lxml and bs4 —if you were using a different parsing library or BS3, I can try it that way).

And when I run it, it seems to work. It's 31.73% complete, with no errors yet. Even if I do a sys.setrecusionlimit(50) at the start of the file, it still seems to work (3.67% complete so far).

So, whatever is wrong in your code is apparently in code you haven't showed us.
