You need to narrow the `try` and put it inside another while-loop:

while i<200:
    for domain in domains:
        srch.query = "test site:.%s" % domain
        while True:
            try:
                res = srch.parse_results()
            except SearchError:
                pass
            else:
                break
        print >> k, res.total_results_available
        i += 1

Cheers,
Chris
