streaming - Python: Record stream and upload to dropbox same time -

i'm recording stream , saving drop-box via python api in 2 steps; 1- record stream , save on local storage 2- pick file local storage , upload drop-box.

i want eliminate local storage, want record stream , same time upload drop-box.

here script,

a function records stream , saves local storage

 stream = urllib.request.urlopen(self.stream_url)             start_time = datetime.now()             dest = open(filename, 'wb')             while (datetime.now() - start_time).seconds / 3600 <= self.duration:                 #print((datetime.datetime.now() - start_time).seconds / 3600)                 dest.write(stream.read(1024))             return filename 

and

client = dropbox.dropbox(self.access_token)         try:             open(file_from, 'rb') f:                 meta = client.files_upload(f.read(), file_to, mute=true)             print("uploaded " + file_to)         except exception e:             print("failed upload " + file_to)             print(e) 

how can this, tried below didn't work;

  while (datetime.now() - start_time).seconds / 3600 <= self.duration:         meta = client.files_upload(dest.write(stream.read(1024)), file_to, mute=true)
