In the code here:
在此处的代码中：
saveFile = open(saveFileLine,'a')
sourceCode = urllib2.urlopen(urlToVisit).read()
splitSource = sourceCode.split
change sourceCode.splitto sourceCode.split().
更改sourceCode.split为sourceCode.split().

如果您想了解有关此错误的更多信息，请阅读以下内容：
When debugging, you'd better remove the try...except block, especially an "expect Exception" block, which is so generic that you will get lost about what is going wrong.
调试时，最好删除 try...except 块，尤其是“expect Exception”块，它非常通用，以至于您会迷失于出错的地方。
When removed the try...except block and run these code again, you will get error info like this:
当删除 try...except 块并再次运行这些代码时，您将获得如下错误信息：

The error message TypeError: 'builtin_function_or_method' object is not iterableis associated with line 25, which means splitSourceis a builtin_function_or_methodand is not iterable.
错误消息TypeError: 'builtin_function_or_method' object is not iterable与第 25 行相关联，这意味着splitSource是 abuiltin_function_or_method和不是iterable。
What is splitSource? It is sourceCode.split. Here comes the answer. You should call a method by using (), without which you will get the method itself. The method str.splitis obviously not iterable!
什么是splitSource？它是sourceCode.split。答案来了。您应该使用 using 调用方法()，否则您将获得方法本身。方法str.split显然不行iterable！
