Not without a totally separate interpreter. If rexec were so easy

Using a separate interpreter could be a solution, but restarting any

work as slow as a CGI app even if it runs using FastCGI.

In an effort to get python2.4 on my Centos 3.7, I installed the python

When you think of modifying the interpreter, think of the compiler
module.

Have you looked at SimPy? This may simplify much of your data

refs), plus it will do

Hi All
Can any one help me out with the various depricated string functions
that is followed in Python.
For example how will be string.lower depricated.
As far as string.lower('PYTHON') is concerned it is depricated as
'PYTHON'.lower(). Both of them would return an output : >>> python

Python properties allow you to get rid of methods like c.getAttr(),
c.setAttr(v), c.delAttr() and replace them with simple constructs like
c.attr, c.attr=v and del c.attr.
If you have been using Java or C++ you know that as soon as you code
your class you have to start filling in the get()
