using PyShell, or other shells?

[John Salerno]

I'm interested in trying out shells other than IDLE, and I found 
PyShell, but I'm not sure how to get it exactly. Is there a way to get 
it without installing wxPython, or is it a part of it? I can't find much 
reference to it in any of the manuals at wxpython.org (except for a 
brief description of what it is, but not *where* it is or how to use it).

Thanks. And if there are other shells that are newer/better, I'd 
appreciate a recommendation.
