I strongly recommend you to read the python tutorial from the official
website, it's really useful.

You should type:

map = mapscript.mapObj("/path/to/mapfile")

or, if using 

from mapscript import * 

(That will work for sure on Unix platforms, dunno in Win)

map = mapObj("/path/to/mapfile")

The getVersion function doesn't exist anymore, now you just type
MS_VERSION

>>> import mapscript
>>> mapscript.MS_VERSION
'3.6.1'

use the dir() function to reveal the actual name of the functions and
constants, for instance my module says:

Python 2.2 (#1, Feb 24 2002, 16:21:58) 
[GCC 2.96 20000731 (Mandrake Linux 8.2 2.96-0.76mdk)] on linux-i386
Type "help", "copyright", "credits" or "license" for more information.
