mediafire scrapper get download_link

I have made a python script thats basically web crawler . My aim is to get direct download links of files from some blogspot and then find-out direct download link.

def trade_spider(max_pages):
page=1
i=1
while page < max_pages:
    url='http://ift.tt/1JBhCIO'
    source_code=requests.get(url)
    plain_text=source_code.text
    soup=BeautifulSoup(plain_text)
    for link in soup.findAll('a' , href=re.compile('http://ift.tt/1Kv9L2l')):

        href=link.get('href')
        print('link no ' + str(i) +'    title   ' + link.string)
        i+=1
        print(href)
        get_download_link(href)
    page+=1

def get_download_link(url):
    source_code = requests.get(url)
    plain_text = source_code.text
    soup = BeautifulSoup(plain_text)
    for link in soup.findAll('div', {"class": "download_link"}):
        href = link.get('href')
        print('Download link ')
        print(href)
