Reading .docx and .txt files (through Box Application client) without downloading them using Python API

Hi! I would like to read the content of the text files in an enterprise's Box Folder without downloading the file(s) on to my local machine for processing. The purpose is to avoid downloading files (thereby not creating their direct readable local copies) from cloud for analysis and directly stream the file's content from cloud. 

I have created a Box App and enabled the necessary permissions for reading and writing files in folders. Is it possible to stream the content of text files using Box API without downloading the files using API? 

I have spent three weeks and could not figure it out. Any help is very much appreciated.
