As a general recommendation, use strace(1) to answer this kind of question. Run "strace -o tmp netstat", then inspect tmp to find out how netstat obtained the information it reported. As Sybren suggests, this can all be answered from /proc. For a process you are interested in, list /proc/<pid>/fd (using os.listdir), then read the contents of all links (using os.readlink). If the link value starts with "[socket:", it's a socket. Then search /proc/net/tcp for the ID. The line containing the ID will have the information you want.
