Okey I tried what you recommended My C:\Python24\sitecustomize.py looks like this:
# sitecustomize.py import os from btools import * When I enter C:\Python24>C:\Python24\pythonw.exe C:\Python24\Lib\idlelib\idle.py -r C:\Python24\sitecustomize.py in commad propmt IDLE starts up and automatically imports 'os' and all names from my btools folder. So far so good. But when I hit Ctrl+F6 and restart Python Shell both 'os' and names from btools are gone! When I work with IDLE I typically start a new file (File/New Window) and when I have written the code I hit (Ctrl+S) to Save and F5 to run. This restarts Python Shell and my names from btools are gone. It's no solution if I'm forced to go back to command prompt and enter the long sequance again.
