The os module has mostly lower level OS interfaces;  there are
sometimes higher level equivalents elsewhere in the language.

It's not bad to use os, but for EG, file operations
os.open/os.read/os.write/os.close, it's better to use "with open as
file_", file_.read, file_.write.

Another example is os.fork() - you can use it, but you're probably
better off with the subprocess module or the multiprocessing module.

You don't really have to worry about breaking anything by using the os
module - at least, not particularly more than the higher level
interfaces for the same thing.
