How to read and write a file at the same time in Python?

Question

Python

Is it possible to simultaneously record audio to a file and at the same time listen to its contents? If this is possible, then I would like to know about the implementation of this on the VLC and Wavio modules in Python. Thanks in advance!

It's not about multithreading, or rather not about it alone.
Try reading the file in chunks into a buffer, save the position, and close the file. Wavio is minimalistic, it has only a couple of functions and it does not know how to set the position. But inside there is a wave that has tell and setpos.
When recording, pay attention to buffering, i.e. when exactly is writing to disk.
