Question

I have a batch file that’s supposed to set PATH/PYTHON path variables and then invoke my python script (myscript.py), that’s designed as an interactive console. I tried with the following:

@echo off
setlocal

if not defined PYTHONHOME (echo warning: PYTHONHOME environment variable is not defined. Using C:\Python24 by default.
SET PYTHONHOME=C:\Python24
if not exist "C:\Python24" ( echo warning: C:\Python24 does not exists. Please specify PYTHONHOME variable manually.))

color 1e
set PYTHONSTARTUP=%~dp0%myscript.py
set PYTHONPATH=%~dp0;%PYTHONPATH%
path %PYTHONHOME%;%PATH%
set PATHEXT=%PATHEXT%;.PY
cd %~dp0%
cmd.exe /k title Interactive Python Console 1.0
cls
%~dp0%myscript.py"

:done
endlocal

Before setting the colorpair (1e)for the console, I have appended directory containing myscript to path, python path and python24 is set as python home.
My problem is:
I am able to change the default font/background color of console, set the current window’s title, but then neither cls (clearscreen) works, nor does my script is invoked. At the console, my pwd is script’s directory. But when i enter ‘python’ at the prompt, myscript is invoked and I can see interactive console of my script.
Anything missing from batch, that would automatically clear off the console after setting color/title, and invoke myscript.py?

This doesn’t really have anything to do with Python. cmd /k doesn’t “set the window title”, it starts a new command shell and leaves you in it, thus stopping your script midway through. Why don’t you just do title My New Title? There’s no need to use cmd.
