Python - Inhibit creation of temporary files

I have a continuously running python process that creates temporary files that I don't know how to read. I've tried using open with 'rb' and np.fromfile with float and int but the results don't make sense. I am honestly not sure when Python decides to make a temporary file, but regardless, since I can't interpret the data, can I prevent creation of the files in the first place? They fill up the hard drive and then crash the process.

**Edit:**The timing is such that I think a temp file is created every time I download a file from the internet with urllib.request. video, _http = urllib.request.urlretrieve(video_path)

Historical: I think python is creating the temporary files because I ran this utility (fnotifystat) that tells me when a file is touched in my /tmp/ directory. 

Total   Open  Close   Read  Write   PID  Process         Pathname
152.0    2.0    1.0    6.0  143.0  18978 python          /tmp/tmpqsj_h99n
  4.0    1.0    1.0    0.0    2.0  18978 python          /tmp/x13i7gh5

Total   Open  Close   Read  Write   PID  Process         Pathname
 32.0    0.0    0.0   32.0    0.0  18978 python          /tmp/tmpqsj_h99n

urllib.request.urlretrieve does indeed create temporary files. urllib.request.urlcleanup() removes them.
