Secure delete with python

[Boris Genc]

Hi everybody.
I was wandering is there a method or a function already implemented in
python that supports secure deletion of data?

I'm interested in something which is able to securely wipe data (from
single file to bunch of MB's), and that should run both on Linux and
Windows.

I tried on google, but I hadn't found anything useful to me.

Thank you very much in advance.
