The main reason is that why do you wish implement a portscan, when is
there a portscan efficient as nmap? (You're loosing time, that IMHO i
should prefer employ in a better way as Italian..i love girls...).
You can argue that you want learn how works a portscanner, but at that
point...read the nmap code. If you want simply learn to program in
Python, you should start with something simpler than a portscanner "ala
nmap" like a personal diary or a notebook, or a contact list.
There's a book that it does for you:

If you want "wrap" nmap in order to create something like:

import nmap

def callback(resultSet):
                for host in resultSet:
                        host.printHostName()
                        host.printOS()

if __name__=='__main__':
        
        nmap_scanner = name.Nmap()
        nmap_options =
nmap.NmapOptions(nmap.STEALTH_SYN_SCAN,nmap.OS_FINGER_PRINT)
        nmap_scanner.setOptions(nmap_options)
        nmap_scanner.start(callback)



It will be great because every sysadm  will be able to customize its
Python scripts in order to do networks checks. But that's a lot of work:
 
* First of all you need a deep understand on how nmap work: create a
some kind of api for nmap.
* Second wrapping with C/C++ Python binding.

Just my 1 cent,

Ciao
Giorgio.
