How to take data from variable and put it into another

Question

i'm having a little bit of an issue: I would like to take this data,

for item in g_data:
    print item.contents[1].find_all("a", {"class":"a-link-normal s-access-detail-page a-text-normal"})[0]["href"]
    print item.contents[1].find_all("a", {"class":"a-link-normal s-access-detail-page a-text-normal"})[1]["href"]
    print item.contents[1].find_all("a", {"class":"a-link-normal s-access-detail-page a-text-normal"})[2]["href"]
    print item.contents[1].find_all("a", {"class":"a-link-normal s-access-detail-page a-text-normal"})[3]["href"]

and use the results in another process.

The code currently prints out the urls of the first page of an amazon search term, I would like to take those urls and then scrape the data on the page. How would I go about making it so that it would be something like this:

If for item in g_data returns url, taker url[1:15] and do 'x' with it.

If for item in g_data does not return url, say "No urls to work with".

Any help or leads you could give would be great, thanks once again.

If you want to take each item in g_data, find all urls in the item and if there are any, do x with them, if there are no urls in the item, then just print something, then this should work:

def do_x(url):
    """ Does x with the given url. """
    short = url[1:15]
    # do x with short
    # ...

# process all items in g_data
for item in g_data:
    # find all links in the item
    links = item.contents[1].find_all("a", {"class":"a-link-normal s-access-detail-page a-text-normal"})

    if not links:
        # no links in this item -> skip
        print("No urls to work with.")
        continue

    # process all links
    for link in links:
        urls = link["href"]
        # process each url
        for url in urls:
            do_x(url)

Is this what you wanted?
