idle python,Python IDLE：更改Python版本

I have Python 2.x and 3.x on my machine (Mac OS X 10.6).

For some things I want to use ver 2, but for others I want ver 3. I like the IDLE software for editing/running, but it always uses version 3.

Is there any way to change the version of the interpreter that IDLE uses?

Thanks!

There are different versions of IDLE installed for each Python version. Depending on how you installed Python on Mac OS X, you may find different folders in /Applications. Look for a Python 3.n (n = 1 or 2) folder with an IDLE in it. Or, from a terminal command line, you may find an idle2.6 and an idle3 or idle3.1 or idle3.2.
