Python3 convert byte object to file object

I am using an API that only takes file objects (a BufferedRandom object returned by open(file_name, 'r+b')).

However, what I have in hand is a variable (bytes object, returned by with open(file_name, "rb") as file: file.read())

I am wondering how to convert this bytes object into the BufferedRandom object to serve as input of the API, because if I input the bytes object as input to the API function, I got the error "bytes" object has no attribute "read".

Thank you very much!

Found an answer here.

You can get your bytes data into a file object with this:

import io
f = io.BytesIO(raw_bytes_data)

Now f behaves just like a file object with methods like read, seek etc. I had a similar issue when I needed to download (export) files from one REDCap database and upload (import) them into another using PyCap. The export_file method returns the file contents as a raw bytestream, while import_file needs a file object. Works with Python 3.
