You already use it (or at least, it was in your code at one point - it seems to have vanished from your finished version). You can use sleep like this:

(Toggle Plain Text)

import time
time.sleep(10)    # sleep for 10 seconds

Or like this:

(Toggle Plain Text)

from time import sleep
sleep(10)         # sleep for 10 seconds

Note the difference between "import" and "from ... import ...".

The same holds true for any module:

(Toggle Plain Text)

import some_module
some_module.some_function()

from some_module import some_function
some_function()

Maybe something like:

(Toggle Plain Text)

        for company_url in get_company_urls(company_index):
                if cache.has_key(company_url):
                        file.write(get_company_data(company_url))
                        print get_company_data(company_url)

                        # And remember to pause so the server isn't overloaded:
                        sleep(1)
