Hi David,

you might checkout embedding your Python 1.5.2 interpreter into Python
using ctypes. Just follow chap.5 of the "Extending and Embedding"
tutorial and the docs of the cytpes API.

The following little script runs successfully on Python23 interpreter.


import ctypes
python24 = ctypes.cdll.LoadLibrary("python24.dll")
python24.PyRun_SimpleString("from time import time,ctime\n")
python24.PyRun_SimpleString("print 'Today is',ctime(time())\n");
