I recently installed Python 3.3 on Centos 6 (which has Python 2.6.6 already installed). When I try to open the the Python Shell with IDLE, it opens with Python 2.6.6.
How do I open Python 3.3 with IDLE?
On my Ubunto 16.04 system, I installed idle3: sudo apt install idle3
Then executing "idle3" brings up a Python 3 window.
idleandidle3. Different flavor, but have you checked for tab completion options in your terminal (type idle and hit tab a few times to see if it shows other executables). – nerdwaller Jun 08 '13 at 05:46
