Embedding python and multiple separate scripts

Hi, I'm trying to embed python into an chat bot I've made in c++. After googling around and reading docs for almost a day I have a few questions. First of all it seems like the best way to be able to run separate scripts in different, isolated environments is to create a sub-interpreter (by us

Mechanize - Click a table row to navigate to detail page

A search form returns a list of records embedded in a table. The user has to click on a table row to call a Javascript call that opens up the detail page. It's the detail page, of course, that really contains the useful information. How can I use Mechanize to click a row? Any ideas? -- http:/

I'm actually using mechanize, but that's too complicated for testing purposes. Instead, I've simulated in a urllib2 sample below an attempt to test for a valid URL request. I'm attempting to craft a loop that will trap failed attempts to request a URL (in cases where the connection intermittently
