我在这里有这个尾递归函数:

def recursiveFunction(n, sum):
    if n < 1:
        return sum
    else:
        return recursiveFunction(n-1, sum+n)

c = 998
print(recursiveFunction(c, 0))

它可以工作到n = 997,然后它就会中断并吐出"比较时超出的最大递归深度" RuntimeError.这只是一个堆栈溢出？有办法解决它吗？

这是一个beautifulsoup抓取所有<p>html标签内容的过程.从某些网页抓取内容后,我收到一条错误,指出超出了最大递归深度.

def printText(tags):
    for tag in tags:
        if tag.__class__ == NavigableString:
            print tag,
        else:
            printText(tag)
    print ""
#loop over urls, send soup to printText procedure

追踪的底部:

 File "web_content.py", line 16, in printText
    printText(tag)
  File "web_content.py", line 16, in printText
    printText(tag)

    if tag.__class__ == NavigableString:
