[Python] Python and forcing the download of a file

I currently have the below code which works great as long as the response on the GET has the content-disposition header. However the problem comes in when there is no header. Normally this would indicate viewing the file in the browser. Is there a way to force the download from within Python?

def action_download(doc_list):
i = 0
for doc in doc_list:
try:
r = requests.get(doc)
filename = re.search('filename="(.*)"', r.headers['content-disposition']).group(1)
with open(filename, "w") as code:
i += 1
code.write(r.content)
code.close()
except requests.exceptions.ConnectionError:
print '\nError: File Not Found Server Side'
print doc
except Exception:
print '\nUnknown Error'
print doc
print r.headers
traceback.print_exc()
continue
if i < 1:
sys.exit()


UPDATED CODE BASED ON RESPONSES

Defining the filename and passing the data content via hte write function works perfectly. Updated code below for anyone coming across the problem.

*Note the addition in the KeyError exception.

def action_download(doc_list):
i = 0
for doc in doc_list:
try:
r = requests.get(doc)
filename = re.search('filename="(.*)"', r.headers['content-disposition']).group(1)
with open(filename, "w") as code:
i += 1
code.write(r.content)
code.close()
except requests.exceptions.ConnectionError:
print '\nError: File Not Found Server Side'
print doc
except KeyError:
temp = str(doc).rsplit('.', 1)[1]
ext = re.sub(r'\?.*', r'', temp)
filename = "file{}.{}".format(i, ext.replace('?T', ''))
with open(filename, "w") as code:
i += 1
code.write(r.content)
code.close()
continue
except Exception:
print '\nUnknown Error'
print doc
print r.headers
traceback.print_exc()
continue
if i < 1:
sys.exit()
