Question

I want to bring up a python window (could be idle or cmd based) with some packages already imported by double clicking a python script. Is this possible? If so, how do I do it?

Answer 1

Sure. You want something like this:

import sys
import code

preloaded_modules = dict(sys=sys)

code.interact(local=preloaded_modules)

When you put the above code in a file and run it, you’ll see a traditional Python REPL (interactive interpreter), except the sys module will already be loaded. You can add more modules to your REPL by importing them into your script and adding them to the preloaded_modules dictionary.

The code module also has tools to build all kinds of custom interpreters.

(NOTE: the above refs Python 2.x, but it should be mostly the same in 3.x)
