Is subprocess cross platform?

Question

I am writing a Network Monitoring application using PySide and Qt. I want to make it cross platform. I am using tcpdump and nmap for a lot of the monitoring portion. There is a nmap python module, but there is no tcpdump python module(that I know of), which means I would have to use subprocess to run tcpdump. So my question is, if I use subprocess, will it work on all platforms (windows, linux, mac) or is it specific to a certain platform?

Answer 1

The subprocess module is cross-platform. It works on POSIX (incl. Mac OS X) and Windows platforms.

There are some caveats and differences that apply only to Windows, all documented in the module documentation .
